Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80398, here are decompositions:

  • 11 + 80387 = 80398
  • 29 + 80369 = 80398
  • 89 + 80309 = 80398
  • 167 + 80231 = 80398
  • 191 + 80207 = 80398
  • 251 + 80147 = 80398
  • 257 + 80141 = 80398
  • 347 + 80051 = 80398

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 80398 first appears in π at position 88,766 of the decimal expansion (the 88,766ordinal-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.
