Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547444, here are decompositions:

  • 3 + 31547441 = 31547444
  • 31 + 31547413 = 31547444
  • 127 + 31547317 = 31547444
  • 157 + 31547287 = 31547444
  • 163 + 31547281 = 31547444
  • 241 + 31547203 = 31547444
  • 283 + 31547161 = 31547444
  • 367 + 31547077 = 31547444

Showing the first eight; more decompositions exist.
