Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 98780, here are decompositions:

  • 7 + 98773 = 98780
  • 43 + 98737 = 98780
  • 67 + 98713 = 98780
  • 139 + 98641 = 98780
  • 307 + 98473 = 98780
  • 313 + 98467 = 98780
  • 337 + 98443 = 98780
  • 373 + 98407 = 98780

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 98780 first appears in π at position 60,261 of the decimal expansion (the 60,261ordinal-suffix:st 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.
