Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547382, here are decompositions:

  • 43 + 31547339 = 31547382
  • 79 + 31547303 = 31547382
  • 101 + 31547281 = 31547382
  • 151 + 31547231 = 31547382
  • 173 + 31547209 = 31547382
  • 179 + 31547203 = 31547382
  • 239 + 31547143 = 31547382
  • 281 + 31547101 = 31547382

Showing the first eight; more decompositions exist.
