Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546422, here are decompositions:

  • 29 + 31546393 = 31546422
  • 53 + 31546369 = 31546422
  • 71 + 31546351 = 31546422
  • 73 + 31546349 = 31546422
  • 139 + 31546283 = 31546422
  • 191 + 31546231 = 31546422
  • 223 + 31546199 = 31546422
  • 241 + 31546181 = 31546422

Showing the first eight; more decompositions exist.
