Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456954, here are decompositions:

  • 5 + 31456949 = 31456954
  • 17 + 31456937 = 31456954
  • 71 + 31456883 = 31456954
  • 167 + 31456787 = 31456954
  • 173 + 31456781 = 31456954
  • 227 + 31456727 = 31456954
  • 233 + 31456721 = 31456954
  • 251 + 31456703 = 31456954

Showing the first eight; more decompositions exist.
