Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29808, here are decompositions:

  • 5 + 29803 = 29808
  • 19 + 29789 = 29808
  • 47 + 29761 = 29808
  • 67 + 29741 = 29808
  • 137 + 29671 = 29808
  • 139 + 29669 = 29808
  • 167 + 29641 = 29808
  • 179 + 29629 = 29808

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 29808 first appears in π at position 28,805 of the decimal expansion (the 28,805ordinal-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.
