Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513298, here are decompositions:

  • 79 + 31513219 = 31513298
  • 97 + 31513201 = 31513298
  • 151 + 31513147 = 31513298
  • 181 + 31513117 = 31513298
  • 241 + 31513057 = 31513298
  • 307 + 31512991 = 31513298
  • 457 + 31512841 = 31513298
  • 541 + 31512757 = 31513298

Showing the first eight; more decompositions exist.
