Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31451174, here are decompositions:

  • 3 + 31451171 = 31451174
  • 127 + 31451047 = 31451174
  • 277 + 31450897 = 31451174
  • 283 + 31450891 = 31451174
  • 331 + 31450843 = 31451174
  • 373 + 31450801 = 31451174
  • 571 + 31450603 = 31451174
  • 631 + 31450543 = 31451174

Showing the first eight; more decompositions exist.
