Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10858, here are decompositions:

  • 5 + 10853 = 10858
  • 11 + 10847 = 10858
  • 59 + 10799 = 10858
  • 149 + 10709 = 10858
  • 167 + 10691 = 10858
  • 191 + 10667 = 10858
  • 227 + 10631 = 10858
  • 251 + 10607 = 10858

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 10858 first appears in π at position 60,813 of the decimal expansion (the 60,813ordinal-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.
