Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526222, here are decompositions:

  • 31 + 31526191 = 31526222
  • 139 + 31526083 = 31526222
  • 241 + 31525981 = 31526222
  • 271 + 31525951 = 31526222
  • 313 + 31525909 = 31526222
  • 331 + 31525891 = 31526222
  • 373 + 31525849 = 31526222
  • 439 + 31525783 = 31526222

Showing the first eight; more decompositions exist.
