Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516442, here are decompositions:

  • 5 + 516437 = 516442
  • 11 + 516431 = 516442
  • 71 + 516371 = 516442
  • 83 + 516359 = 516442
  • 149 + 516293 = 516442
  • 191 + 516251 = 516442
  • 233 + 516209 = 516442
  • 263 + 516179 = 516442

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 516,442 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 516442 first appears in π at position 771,874 of the decimal expansion (the 771,874ordinal-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.
