Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513998, here are decompositions:

  • 7 + 513991 = 513998
  • 61 + 513937 = 513998
  • 127 + 513871 = 513998
  • 157 + 513841 = 513998
  • 229 + 513769 = 513998
  • 271 + 513727 = 513998
  • 307 + 513691 = 513998
  • 349 + 513649 = 513998

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 513,998 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 513998 first appears in π at position 491,323 of the decimal expansion (the 491,323ordinal-suffix:rd 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.
