Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539298, here are decompositions:

  • 107 + 31539191 = 31539298
  • 251 + 31539047 = 31539298
  • 311 + 31538987 = 31539298
  • 347 + 31538951 = 31539298
  • 491 + 31538807 = 31539298
  • 509 + 31538789 = 31539298
  • 569 + 31538729 = 31539298
  • 587 + 31538711 = 31539298

Showing the first eight; more decompositions exist.
