Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 519972, here are decompositions:

  • 29 + 519943 = 519972
  • 41 + 519931 = 519972
  • 53 + 519919 = 519972
  • 83 + 519889 = 519972
  • 109 + 519863 = 519972
  • 179 + 519793 = 519972
  • 239 + 519733 = 519972
  • 269 + 519703 = 519972

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 519,972 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 519972 first appears in π at position 192,535 of the decimal expansion (the 192,535ordinal-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.
