Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488220, here are decompositions:

  • 11 + 488209 = 488220
  • 13 + 488207 = 488220
  • 17 + 488203 = 488220
  • 23 + 488197 = 488220
  • 59 + 488161 = 488220
  • 67 + 488153 = 488220
  • 71 + 488149 = 488220
  • 101 + 488119 = 488220

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 488,220 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 488220 first appears in π at position 547,206 of the decimal expansion (the 547,206ordinal-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.
