Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550762, here are decompositions:

  • 31 + 31550731 = 31550762
  • 151 + 31550611 = 31550762
  • 163 + 31550599 = 31550762
  • 181 + 31550581 = 31550762
  • 193 + 31550569 = 31550762
  • 223 + 31550539 = 31550762
  • 283 + 31550479 = 31550762
  • 409 + 31550353 = 31550762

Showing the first eight; more decompositions exist.
