Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72416, here are decompositions:

  • 37 + 72379 = 72416
  • 79 + 72337 = 72416
  • 103 + 72313 = 72416
  • 109 + 72307 = 72416
  • 139 + 72277 = 72416
  • 163 + 72253 = 72416
  • 193 + 72223 = 72416
  • 277 + 72139 = 72416

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 72416 first appears in π at position 128,573 of the decimal expansion (the 128,573ordinal-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.
