Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455052, here are decompositions:

  • 11 + 31455041 = 31455052
  • 53 + 31454999 = 31455052
  • 149 + 31454903 = 31455052
  • 179 + 31454873 = 31455052
  • 269 + 31454783 = 31455052
  • 311 + 31454741 = 31455052
  • 383 + 31454669 = 31455052
  • 401 + 31454651 = 31455052

Showing the first eight; more decompositions exist.
