Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15882, here are decompositions:

  • 5 + 15877 = 15882
  • 23 + 15859 = 15882
  • 59 + 15823 = 15882
  • 73 + 15809 = 15882
  • 79 + 15803 = 15882
  • 109 + 15773 = 15882
  • 149 + 15733 = 15882
  • 151 + 15731 = 15882

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 15882 first appears in π at position 38,352 of the decimal expansion (the 38,352ordinal-suffix:nd 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.
