Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626634, here are decompositions:

  • 71 + 31626563 = 31626634
  • 101 + 31626533 = 31626634
  • 173 + 31626461 = 31626634
  • 197 + 31626437 = 31626634
  • 227 + 31626407 = 31626634
  • 251 + 31626383 = 31626634
  • 257 + 31626377 = 31626634
  • 311 + 31626323 = 31626634

Showing the first eight; more decompositions exist.
