Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15382, here are decompositions:

  • 5 + 15377 = 15382
  • 23 + 15359 = 15382
  • 53 + 15329 = 15382
  • 83 + 15299 = 15382
  • 113 + 15269 = 15382
  • 149 + 15233 = 15382
  • 233 + 15149 = 15382
  • 251 + 15131 = 15382

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 15382 first appears in π at position 240,161 of the decimal expansion (the 240,161ordinal-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.
