Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147466642, here are decompositions:

  • 53 + 2147466589 = 2147466642
  • 103 + 2147466539 = 2147466642
  • 163 + 2147466479 = 2147466642
  • 179 + 2147466463 = 2147466642
  • 193 + 2147466449 = 2147466642
  • 283 + 2147466359 = 2147466642
  • 313 + 2147466329 = 2147466642
  • 359 + 2147466283 = 2147466642

Showing the first eight; more decompositions exist.
