Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486126, here are decompositions:

  • 3 + 31486123 = 31486126
  • 5 + 31486121 = 31486126
  • 17 + 31486109 = 31486126
  • 167 + 31485959 = 31486126
  • 173 + 31485953 = 31486126
  • 233 + 31485893 = 31486126
  • 293 + 31485833 = 31486126
  • 359 + 31485767 = 31486126

Showing the first eight; more decompositions exist.
