Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487160, here are decompositions:

  • 61 + 487099 = 487160
  • 67 + 487093 = 487160
  • 103 + 487057 = 487160
  • 109 + 487051 = 487160
  • 139 + 487021 = 487160
  • 211 + 486949 = 487160
  • 379 + 486781 = 487160
  • 439 + 486721 = 487160

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 487,160 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 487160 first appears in π at position 421,334 of the decimal expansion (the 421,334ordinal-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.
