Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502956, here are decompositions:

  • 3 + 31502953 = 31502956
  • 29 + 31502927 = 31502956
  • 59 + 31502897 = 31502956
  • 179 + 31502777 = 31502956
  • 257 + 31502699 = 31502956
  • 269 + 31502687 = 31502956
  • 467 + 31502489 = 31502956
  • 593 + 31502363 = 31502956

Showing the first eight; more decompositions exist.
