Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463078, here are decompositions:

  • 109 + 31462969 = 31463078
  • 181 + 31462897 = 31463078
  • 271 + 31462807 = 31463078
  • 307 + 31462771 = 31463078
  • 331 + 31462747 = 31463078
  • 349 + 31462729 = 31463078
  • 487 + 31462591 = 31463078
  • 499 + 31462579 = 31463078

Showing the first eight; more decompositions exist.
