Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 54780, here are decompositions:

  • 7 + 54773 = 54780
  • 13 + 54767 = 54780
  • 29 + 54751 = 54780
  • 53 + 54727 = 54780
  • 59 + 54721 = 54780
  • 67 + 54713 = 54780
  • 71 + 54709 = 54780
  • 101 + 54679 = 54780

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 54780 first appears in π at position 61,289 of the decimal expansion (the 61,289ordinal-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.
