Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547636, here are decompositions:

  • 7 + 31547629 = 31547636
  • 19 + 31547617 = 31547636
  • 79 + 31547557 = 31547636
  • 97 + 31547539 = 31547636
  • 157 + 31547479 = 31547636
  • 223 + 31547413 = 31547636
  • 349 + 31547287 = 31547636
  • 433 + 31547203 = 31547636

Showing the first eight; more decompositions exist.
