Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147396618, here are decompositions:

  • 61 + 2147396557 = 2147396618
  • 97 + 2147396521 = 2147396618
  • 277 + 2147396341 = 2147396618
  • 337 + 2147396281 = 2147396618
  • 439 + 2147396179 = 2147396618
  • 541 + 2147396077 = 2147396618
  • 691 + 2147395927 = 2147396618
  • 727 + 2147395891 = 2147396618

Showing the first eight; more decompositions exist.
