Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471070, here are decompositions:

  • 19 + 31471051 = 31471070
  • 73 + 31470997 = 31471070
  • 79 + 31470991 = 31471070
  • 157 + 31470913 = 31471070
  • 181 + 31470889 = 31471070
  • 223 + 31470847 = 31471070
  • 271 + 31470799 = 31471070
  • 277 + 31470793 = 31471070

Showing the first eight; more decompositions exist.
