Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521474, here are decompositions:

  • 3 + 521471 = 521474
  • 73 + 521401 = 521474
  • 97 + 521377 = 521474
  • 157 + 521317 = 521474
  • 193 + 521281 = 521474
  • 223 + 521251 = 521474
  • 307 + 521167 = 521474
  • 313 + 521161 = 521474

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 521,474 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 521474 first appears in π at position 532,543 of the decimal expansion (the 532,543ordinal-suffix:rd 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.
