Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547346, here are decompositions:

  • 7 + 31547339 = 31547346
  • 29 + 31547317 = 31547346
  • 43 + 31547303 = 31547346
  • 59 + 31547287 = 31547346
  • 79 + 31547267 = 31547346
  • 137 + 31547209 = 31547346
  • 199 + 31547147 = 31547346
  • 269 + 31547077 = 31547346

Showing the first eight; more decompositions exist.
