Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513848, here are decompositions:

  • 7 + 513841 = 513848
  • 19 + 513829 = 513848
  • 67 + 513781 = 513848
  • 79 + 513769 = 513848
  • 109 + 513739 = 513848
  • 151 + 513697 = 513848
  • 157 + 513691 = 513848
  • 199 + 513649 = 513848

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 513,848 and was likely granted around 1893.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 513848 first appears in π at position 427,801 of the decimal expansion (the 427,801ordinal-suffix:st 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.
