Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20794, here are decompositions:

  • 5 + 20789 = 20794
  • 23 + 20771 = 20794
  • 41 + 20753 = 20794
  • 47 + 20747 = 20794
  • 101 + 20693 = 20794
  • 113 + 20681 = 20794
  • 131 + 20663 = 20794
  • 167 + 20627 = 20794

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 20794 first appears in π at position 339,369 of the decimal expansion (the 339,369ordinal-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.
