Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525404, here are decompositions:

  • 7 + 525397 = 525404
  • 13 + 525391 = 525404
  • 31 + 525373 = 525404
  • 43 + 525361 = 525404
  • 151 + 525253 = 525404
  • 157 + 525247 = 525404
  • 163 + 525241 = 525404
  • 211 + 525193 = 525404

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 525,404 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 525404 first appears in π at position 175,887 of the decimal expansion (the 175,887ordinal-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.
