Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31444792, here are decompositions:

  • 3 + 31444789 = 31444792
  • 101 + 31444691 = 31444792
  • 131 + 31444661 = 31444792
  • 149 + 31444643 = 31444792
  • 233 + 31444559 = 31444792
  • 251 + 31444541 = 31444792
  • 389 + 31444403 = 31444792
  • 479 + 31444313 = 31444792

Showing the first eight; more decompositions exist.
