Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518370, here are decompositions:

  • 29 + 518341 = 518370
  • 43 + 518327 = 518370
  • 59 + 518311 = 518370
  • 71 + 518299 = 518370
  • 79 + 518291 = 518370
  • 109 + 518261 = 518370
  • 131 + 518239 = 518370
  • 137 + 518233 = 518370

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 518,370 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 518370 first appears in π at position 604,700 of the decimal expansion (the 604,700ordinal-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.
