Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471082, here are decompositions:

  • 3 + 31471079 = 31471082
  • 31 + 31471051 = 31471082
  • 193 + 31470889 = 31471082
  • 229 + 31470853 = 31471082
  • 283 + 31470799 = 31471082
  • 373 + 31470709 = 31471082
  • 421 + 31470661 = 31471082
  • 463 + 31470619 = 31471082

Showing the first eight; more decompositions exist.
