Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536456, here are decompositions:

  • 53 + 31536403 = 31536456
  • 59 + 31536397 = 31536456
  • 73 + 31536383 = 31536456
  • 97 + 31536359 = 31536456
  • 103 + 31536353 = 31536456
  • 109 + 31536347 = 31536456
  • 163 + 31536293 = 31536456
  • 229 + 31536227 = 31536456

Showing the first eight; more decompositions exist.
