Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488540, here are decompositions:

  • 37 + 488503 = 488540
  • 67 + 488473 = 488540
  • 139 + 488401 = 488540
  • 193 + 488347 = 488540
  • 211 + 488329 = 488540
  • 223 + 488317 = 488540
  • 229 + 488311 = 488540
  • 277 + 488263 = 488540

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 488,540 and was likely granted around 1892.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 488540 first appears in π at position 170,910 of the decimal expansion (the 170,910ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
