Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515048, here are decompositions:

  • 7 + 515041 = 515048
  • 109 + 514939 = 515048
  • 181 + 514867 = 515048
  • 229 + 514819 = 515048
  • 307 + 514741 = 515048
  • 337 + 514711 = 515048
  • 367 + 514681 = 515048
  • 379 + 514669 = 515048

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 515,048 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 515048 first appears in π at position 739,798 of the decimal expansion (the 739,798ordinal-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.
