Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547358, here are decompositions:

  • 19 + 31547339 = 31547358
  • 41 + 31547317 = 31547358
  • 61 + 31547297 = 31547358
  • 71 + 31547287 = 31547358
  • 97 + 31547261 = 31547358
  • 127 + 31547231 = 31547358
  • 149 + 31547209 = 31547358
  • 181 + 31547177 = 31547358

Showing the first eight; more decompositions exist.
