Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468320, here are decompositions:

  • 31 + 31468289 = 31468320
  • 61 + 31468259 = 31468320
  • 73 + 31468247 = 31468320
  • 89 + 31468231 = 31468320
  • 97 + 31468223 = 31468320
  • 109 + 31468211 = 31468320
  • 151 + 31468169 = 31468320
  • 173 + 31468147 = 31468320

Showing the first eight; more decompositions exist.
