Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42206, here are decompositions:

  • 13 + 42193 = 42206
  • 19 + 42187 = 42206
  • 37 + 42169 = 42206
  • 67 + 42139 = 42206
  • 163 + 42043 = 42206
  • 193 + 42013 = 42206
  • 223 + 41983 = 42206
  • 313 + 41893 = 42206

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 42206 first appears in π at position 142,009 of the decimal expansion (the 142,009ordinal-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.
