Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77806, here are decompositions:

  • 5 + 77801 = 77806
  • 23 + 77783 = 77806
  • 59 + 77747 = 77806
  • 83 + 77723 = 77806
  • 107 + 77699 = 77806
  • 233 + 77573 = 77806
  • 257 + 77549 = 77806
  • 263 + 77543 = 77806

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 77806 first appears in π at position 96,737 of the decimal expansion (the 96,737ordinal-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.
