Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526258, here are decompositions:

  • 19 + 31526239 = 31526258
  • 31 + 31526227 = 31526258
  • 37 + 31526221 = 31526258
  • 61 + 31526197 = 31526258
  • 67 + 31526191 = 31526258
  • 277 + 31525981 = 31526258
  • 307 + 31525951 = 31526258
  • 331 + 31525927 = 31526258

Showing the first eight; more decompositions exist.
