Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18846, here are decompositions:

  • 7 + 18839 = 18846
  • 43 + 18803 = 18846
  • 53 + 18793 = 18846
  • 59 + 18787 = 18846
  • 73 + 18773 = 18846
  • 89 + 18757 = 18846
  • 97 + 18749 = 18846
  • 103 + 18743 = 18846

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 18846 first appears in π at position 15,937 of the decimal expansion (the 15,937ordinal-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.
