Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486248, here are decompositions:

  • 19 + 31486229 = 31486248
  • 47 + 31486201 = 31486248
  • 127 + 31486121 = 31486248
  • 139 + 31486109 = 31486248
  • 239 + 31486009 = 31486248
  • 307 + 31485941 = 31486248
  • 317 + 31485931 = 31486248
  • 331 + 31485917 = 31486248

Showing the first eight; more decompositions exist.
