Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547360, here are decompositions:

  • 3 + 31547357 = 31547360
  • 43 + 31547317 = 31547360
  • 73 + 31547287 = 31547360
  • 79 + 31547281 = 31547360
  • 151 + 31547209 = 31547360
  • 157 + 31547203 = 31547360
  • 199 + 31547161 = 31547360
  • 283 + 31547077 = 31547360

Showing the first eight; more decompositions exist.
