Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455696, here are decompositions:

  • 47 + 31455649 = 31455696
  • 59 + 31455637 = 31455696
  • 73 + 31455623 = 31455696
  • 163 + 31455533 = 31455696
  • 193 + 31455503 = 31455696
  • 197 + 31455499 = 31455696
  • 263 + 31455433 = 31455696
  • 269 + 31455427 = 31455696

Showing the first eight; more decompositions exist.
