Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147518426, here are decompositions:

  • 83 + 2147518343 = 2147518426
  • 197 + 2147518229 = 2147518426
  • 233 + 2147518193 = 2147518426
  • 419 + 2147518007 = 2147518426
  • 593 + 2147517833 = 2147518426
  • 743 + 2147517683 = 2147518426
  • 839 + 2147517587 = 2147518426
  • 863 + 2147517563 = 2147518426

Showing the first eight; more decompositions exist.
