Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147493280, here are decompositions:

  • 3 + 2147493277 = 2147493280
  • 227 + 2147493053 = 2147493280
  • 263 + 2147493017 = 2147493280
  • 521 + 2147492759 = 2147493280
  • 641 + 2147492639 = 2147493280
  • 659 + 2147492621 = 2147493280
  • 683 + 2147492597 = 2147493280
  • 887 + 2147492393 = 2147493280

Showing the first eight; more decompositions exist.
