Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486534, here are decompositions:

  • 5 + 31486529 = 31486534
  • 41 + 31486493 = 31486534
  • 71 + 31486463 = 31486534
  • 83 + 31486451 = 31486534
  • 197 + 31486337 = 31486534
  • 227 + 31486307 = 31486534
  • 251 + 31486283 = 31486534
  • 263 + 31486271 = 31486534

Showing the first eight; more decompositions exist.
