Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523478, here are decompositions:

  • 19 + 523459 = 523478
  • 61 + 523417 = 523478
  • 127 + 523351 = 523478
  • 181 + 523297 = 523478
  • 271 + 523207 = 523478
  • 349 + 523129 = 523478
  • 457 + 523021 = 523478
  • 607 + 522871 = 523478

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 523,478 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 523478 first appears in π at position 488,356 of the decimal expansion (the 488,356ordinal-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.
