Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33780, here are decompositions:

  • 7 + 33773 = 33780
  • 11 + 33769 = 33780
  • 13 + 33767 = 33780
  • 23 + 33757 = 33780
  • 29 + 33751 = 33780
  • 31 + 33749 = 33780
  • 41 + 33739 = 33780
  • 59 + 33721 = 33780

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 33780 first appears in π at position 70,141 of the decimal expansion (the 70,141ordinal-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.
