Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513606, here are decompositions:

  • 233 + 31513373 = 31513606
  • 347 + 31513259 = 31513606
  • 419 + 31513187 = 31513606
  • 557 + 31513049 = 31513606
  • 569 + 31513037 = 31513606
  • 599 + 31513007 = 31513606
  • 647 + 31512959 = 31513606
  • 659 + 31512947 = 31513606

Showing the first eight; more decompositions exist.
