Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459104, here are decompositions:

  • 11 + 31459093 = 31459104
  • 31 + 31459073 = 31459104
  • 41 + 31459063 = 31459104
  • 73 + 31459031 = 31459104
  • 137 + 31458967 = 31459104
  • 151 + 31458953 = 31459104
  • 167 + 31458937 = 31459104
  • 181 + 31458923 = 31459104

Showing the first eight; more decompositions exist.
