Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8858, here are decompositions:

  • 19 + 8839 = 8858
  • 37 + 8821 = 8858
  • 79 + 8779 = 8858
  • 97 + 8761 = 8858
  • 127 + 8731 = 8858
  • 139 + 8719 = 8858
  • 151 + 8707 = 8858
  • 181 + 8677 = 8858

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 8858 first appears in π at position 1,469 of the decimal expansion (the 1,469ordinal-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.
