Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 98870, here are decompositions:

  • 3 + 98867 = 98870
  • 61 + 98809 = 98870
  • 97 + 98773 = 98870
  • 139 + 98731 = 98870
  • 157 + 98713 = 98870
  • 181 + 98689 = 98870
  • 229 + 98641 = 98870
  • 307 + 98563 = 98870

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 98870 first appears in π at position 21,298 of the decimal expansion (the 21,298ordinal-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.
