Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547340, here are decompositions:

  • 23 + 31547317 = 31547340
  • 37 + 31547303 = 31547340
  • 43 + 31547297 = 31547340
  • 53 + 31547287 = 31547340
  • 59 + 31547281 = 31547340
  • 73 + 31547267 = 31547340
  • 79 + 31547261 = 31547340
  • 109 + 31547231 = 31547340

Showing the first eight; more decompositions exist.
