Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520154, here are decompositions:

  • 3 + 520151 = 520154
  • 31 + 520123 = 520154
  • 43 + 520111 = 520154
  • 157 + 519997 = 520154
  • 211 + 519943 = 520154
  • 223 + 519931 = 520154
  • 337 + 519817 = 520154
  • 367 + 519787 = 520154

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 520,154 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 520154 first appears in π at position 703,687 of the decimal expansion (the 703,687ordinal-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.
