Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515154, here are decompositions:

  • 5 + 515149 = 515154
  • 11 + 515143 = 515154
  • 43 + 515111 = 515154
  • 67 + 515087 = 515154
  • 113 + 515041 = 515154
  • 251 + 514903 = 515154
  • 281 + 514873 = 515154
  • 307 + 514847 = 515154

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 515,154 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 515154 first appears in π at position 834,683 of the decimal expansion (the 834,683ordinal-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.
