Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71748, here are decompositions:

  • 7 + 71741 = 71748
  • 29 + 71719 = 71748
  • 37 + 71711 = 71748
  • 41 + 71707 = 71748
  • 101 + 71647 = 71748
  • 151 + 71597 = 71748
  • 179 + 71569 = 71748
  • 197 + 71551 = 71748

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 71748 first appears in π at position 259,109 of the decimal expansion (the 259,109ordinal-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.
