Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519478, here are decompositions:

  • 107 + 519371 = 519478
  • 191 + 519287 = 519478
  • 251 + 519227 = 519478
  • 317 + 519161 = 519478
  • 347 + 519131 = 519478
  • 359 + 519119 = 519478
  • 389 + 519089 = 519478
  • 467 + 519011 = 519478

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 519,478 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 519478 first appears in π at position 13,697 of the decimal expansion (the 13,697ordinal-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.
