Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 98720, here are decompositions:

  • 3 + 98717 = 98720
  • 7 + 98713 = 98720
  • 31 + 98689 = 98720
  • 79 + 98641 = 98720
  • 157 + 98563 = 98720
  • 229 + 98491 = 98720
  • 241 + 98479 = 98720
  • 277 + 98443 = 98720

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 98720 first appears in π at position 1,510 of the decimal expansion (the 1,510ordinal-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.
