Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518396, here are decompositions:

  • 7 + 518389 = 518396
  • 97 + 518299 = 518396
  • 157 + 518239 = 518396
  • 163 + 518233 = 518396
  • 283 + 518113 = 518396
  • 313 + 518083 = 518396
  • 337 + 518059 = 518396
  • 349 + 518047 = 518396

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 518,396 and was likely granted around 1894.

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

Position in π

The digit sequence 518396 first appears in π at position 302,724 of the decimal expansion (the 302,724ordinal-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.
