Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545862, here are decompositions:

  • 3 + 31545859 = 31545862
  • 113 + 31545749 = 31545862
  • 149 + 31545713 = 31545862
  • 233 + 31545629 = 31545862
  • 239 + 31545623 = 31545862
  • 251 + 31545611 = 31545862
  • 263 + 31545599 = 31545862
  • 461 + 31545401 = 31545862

Showing the first eight; more decompositions exist.
