Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75312, here are decompositions:

  • 5 + 75307 = 75312
  • 23 + 75289 = 75312
  • 43 + 75269 = 75312
  • 59 + 75253 = 75312
  • 73 + 75239 = 75312
  • 89 + 75223 = 75312
  • 101 + 75211 = 75312
  • 103 + 75209 = 75312

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 75312 first appears in π at position 33,510 of the decimal expansion (the 33,510ordinal-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.
