Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540304, here are decompositions:

  • 7 + 31540297 = 31540304
  • 43 + 31540261 = 31540304
  • 97 + 31540207 = 31540304
  • 157 + 31540147 = 31540304
  • 181 + 31540123 = 31540304
  • 241 + 31540063 = 31540304
  • 337 + 31539967 = 31540304
  • 373 + 31539931 = 31540304

Showing the first eight; more decompositions exist.
