Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535992, here are decompositions:

  • 11 + 31535981 = 31535992
  • 53 + 31535939 = 31535992
  • 83 + 31535909 = 31535992
  • 113 + 31535879 = 31535992
  • 239 + 31535753 = 31535992
  • 251 + 31535741 = 31535992
  • 311 + 31535681 = 31535992
  • 353 + 31535639 = 31535992

Showing the first eight; more decompositions exist.
