Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294999986, here are decompositions:

  • 29 + 4294999957 = 4294999986
  • 37 + 4294999949 = 4294999986
  • 47 + 4294999939 = 4294999986
  • 97 + 4294999889 = 4294999986
  • 223 + 4294999763 = 4294999986
  • 269 + 4294999717 = 4294999986
  • 439 + 4294999547 = 4294999986
  • 449 + 4294999537 = 4294999986

Showing the first eight; more decompositions exist.
