Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80370, here are decompositions:

  • 7 + 80363 = 80370
  • 23 + 80347 = 80370
  • 29 + 80341 = 80370
  • 41 + 80329 = 80370
  • 53 + 80317 = 80370
  • 61 + 80309 = 80370
  • 83 + 80287 = 80370
  • 97 + 80273 = 80370

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 80370 first appears in π at position 85,477 of the decimal expansion (the 85,477ordinal-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.
