Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64844, here are decompositions:

  • 61 + 64783 = 64844
  • 97 + 64747 = 64844
  • 127 + 64717 = 64844
  • 151 + 64693 = 64844
  • 181 + 64663 = 64844
  • 211 + 64633 = 64844
  • 223 + 64621 = 64844
  • 277 + 64567 = 64844

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 64844 first appears in π at position 39,000 of the decimal expansion (the 39,000ordinal-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.
