Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545052, here are decompositions:

  • 3 + 31545049 = 31545052
  • 29 + 31545023 = 31545052
  • 83 + 31544969 = 31545052
  • 89 + 31544963 = 31545052
  • 173 + 31544879 = 31545052
  • 233 + 31544819 = 31545052
  • 269 + 31544783 = 31545052
  • 281 + 31544771 = 31545052

Showing the first eight; more decompositions exist.
