Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486184, here are decompositions:

  • 61 + 31486123 = 31486184
  • 97 + 31486087 = 31486184
  • 151 + 31486033 = 31486184
  • 211 + 31485973 = 31486184
  • 313 + 31485871 = 31486184
  • 463 + 31485721 = 31486184
  • 523 + 31485661 = 31486184
  • 601 + 31485583 = 31486184

Showing the first eight; more decompositions exist.
