Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17882, here are decompositions:

  • 19 + 17863 = 17882
  • 31 + 17851 = 17882
  • 43 + 17839 = 17882
  • 199 + 17683 = 17882
  • 223 + 17659 = 17882
  • 283 + 17599 = 17882
  • 313 + 17569 = 17882
  • 331 + 17551 = 17882

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 17882 first appears in π at position 137,746 of the decimal expansion (the 137,746ordinal-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.
