Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487418, here are decompositions:

  • 31 + 487387 = 487418
  • 37 + 487381 = 487418
  • 157 + 487261 = 487418
  • 199 + 487219 = 487418
  • 241 + 487177 = 487418
  • 307 + 487111 = 487418
  • 367 + 487051 = 487418
  • 397 + 487021 = 487418

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 487,418 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 487418 first appears in π at position 81,098 of the decimal expansion (the 81,098ordinal-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.
