Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506046, here are decompositions:

  • 17 + 31506029 = 31506046
  • 53 + 31505993 = 31506046
  • 107 + 31505939 = 31506046
  • 137 + 31505909 = 31506046
  • 233 + 31505813 = 31506046
  • 239 + 31505807 = 31506046
  • 263 + 31505783 = 31506046
  • 317 + 31505729 = 31506046

Showing the first eight; more decompositions exist.
