Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461626, here are decompositions:

  • 73 + 31461553 = 31461626
  • 103 + 31461523 = 31461626
  • 109 + 31461517 = 31461626
  • 139 + 31461487 = 31461626
  • 199 + 31461427 = 31461626
  • 223 + 31461403 = 31461626
  • 277 + 31461349 = 31461626
  • 283 + 31461343 = 31461626

Showing the first eight; more decompositions exist.
