Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 524240, here are decompositions:

  • 19 + 524221 = 524240
  • 37 + 524203 = 524240
  • 43 + 524197 = 524240
  • 127 + 524113 = 524240
  • 193 + 524047 = 524240
  • 271 + 523969 = 524240
  • 313 + 523927 = 524240
  • 337 + 523903 = 524240

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 524,240 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 524240 first appears in π at position 228,101 of the decimal expansion (the 228,101ordinal-suffix:st 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.
