Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 578540, here are decompositions:

  • 3 + 578537 = 578540
  • 7 + 578533 = 578540
  • 31 + 578509 = 578540
  • 37 + 578503 = 578540
  • 43 + 578497 = 578540
  • 73 + 578467 = 578540
  • 139 + 578401 = 578540
  • 223 + 578317 = 578540

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 578,540 and was likely granted around 1896.

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

Position in π

The digit sequence 578540 first appears in π at position 147,879 of the decimal expansion (the 147,879ordinal-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.
