Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526510, here are decompositions:

  • 7 + 31526503 = 31526510
  • 13 + 31526497 = 31526510
  • 79 + 31526431 = 31526510
  • 139 + 31526371 = 31526510
  • 151 + 31526359 = 31526510
  • 193 + 31526317 = 31526510
  • 229 + 31526281 = 31526510
  • 271 + 31526239 = 31526510

Showing the first eight; more decompositions exist.
