Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 21062, here are decompositions:

  • 3 + 21059 = 21062
  • 31 + 21031 = 21062
  • 43 + 21019 = 21062
  • 61 + 21001 = 21062
  • 79 + 20983 = 21062
  • 103 + 20959 = 21062
  • 163 + 20899 = 21062
  • 313 + 20749 = 21062

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 21062 first appears in π at position 30,731 of the decimal expansion (the 30,731ordinal-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.
