Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515168, here are decompositions:

  • 19 + 515149 = 515168
  • 79 + 515089 = 515168
  • 127 + 515041 = 515168
  • 229 + 514939 = 515168
  • 337 + 514831 = 515168
  • 349 + 514819 = 515168
  • 421 + 514747 = 515168
  • 457 + 514711 = 515168

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 515,168 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 515168 first appears in π at position 289,786 of the decimal expansion (the 289,786ordinal-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.
