Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519040, here are decompositions:

  • 3 + 519037 = 519040
  • 29 + 519011 = 519040
  • 59 + 518981 = 519040
  • 107 + 518933 = 519040
  • 173 + 518867 = 519040
  • 227 + 518813 = 519040
  • 233 + 518807 = 519040
  • 239 + 518801 = 519040

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 519,040 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 519040 first appears in π at position 32,257 of the decimal expansion (the 32,257ordinal-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.
