Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525490, here are decompositions:

  • 23 + 525467 = 525490
  • 29 + 525461 = 525490
  • 59 + 525431 = 525490
  • 113 + 525377 = 525490
  • 131 + 525359 = 525490
  • 137 + 525353 = 525490
  • 191 + 525299 = 525490
  • 233 + 525257 = 525490

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 525,490 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 525490 first appears in π at position 918,119 of the decimal expansion (the 918,119ordinal-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.
