Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15832, here are decompositions:

  • 23 + 15809 = 15832
  • 29 + 15803 = 15832
  • 41 + 15791 = 15832
  • 59 + 15773 = 15832
  • 71 + 15761 = 15832
  • 83 + 15749 = 15832
  • 101 + 15731 = 15832
  • 149 + 15683 = 15832

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 15832 first appears in π at position 62,376 of the decimal expansion (the 62,376ordinal-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.
