Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477310, here are decompositions:

  • 19 + 31477291 = 31477310
  • 97 + 31477213 = 31477310
  • 103 + 31477207 = 31477310
  • 199 + 31477111 = 31477310
  • 211 + 31477099 = 31477310
  • 283 + 31477027 = 31477310
  • 379 + 31476931 = 31477310
  • 439 + 31476871 = 31477310

Showing the first eight; more decompositions exist.
