Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20834, here are decompositions:

  • 61 + 20773 = 20834
  • 103 + 20731 = 20834
  • 127 + 20707 = 20834
  • 193 + 20641 = 20834
  • 223 + 20611 = 20834
  • 241 + 20593 = 20834
  • 271 + 20563 = 20834
  • 283 + 20551 = 20834

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 20834 first appears in π at position 32,137 of the decimal expansion (the 32,137ordinal-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.
