Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536228, here are decompositions:

  • 5 + 31536223 = 31536228
  • 41 + 31536187 = 31536228
  • 67 + 31536161 = 31536228
  • 127 + 31536101 = 31536228
  • 131 + 31536097 = 31536228
  • 167 + 31536061 = 31536228
  • 179 + 31536049 = 31536228
  • 211 + 31536017 = 31536228

Showing the first eight; more decompositions exist.
