Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45820, here are decompositions:

  • 3 + 45817 = 45820
  • 41 + 45779 = 45820
  • 53 + 45767 = 45820
  • 83 + 45737 = 45820
  • 113 + 45707 = 45820
  • 179 + 45641 = 45820
  • 233 + 45587 = 45820
  • 251 + 45569 = 45820

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 45820 first appears in π at position 84,661 of the decimal expansion (the 84,661ordinal-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.
