Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147466838, here are decompositions:

  • 5 + 2147466833 = 2147466838
  • 137 + 2147466701 = 2147466838
  • 197 + 2147466641 = 2147466838
  • 317 + 2147466521 = 2147466838
  • 359 + 2147466479 = 2147466838
  • 389 + 2147466449 = 2147466838
  • 479 + 2147466359 = 2147466838
  • 509 + 2147466329 = 2147466838

Showing the first eight; more decompositions exist.
