Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 537648, here are decompositions:

  • 11 + 537637 = 537648
  • 37 + 537611 = 537648
  • 61 + 537587 = 537648
  • 79 + 537569 = 537648
  • 101 + 537547 = 537648
  • 151 + 537497 = 537648
  • 269 + 537379 = 537648
  • 317 + 537331 = 537648

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 537,648 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 537648 first appears in π at position 69,199 of the decimal expansion (the 69,199ordinal-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.
