Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486150, here are decompositions:

  • 29 + 31486121 = 31486150
  • 41 + 31486109 = 31486150
  • 191 + 31485959 = 31486150
  • 197 + 31485953 = 31486150
  • 233 + 31485917 = 31486150
  • 257 + 31485893 = 31486150
  • 317 + 31485833 = 31486150
  • 347 + 31485803 = 31486150

Showing the first eight; more decompositions exist.
