Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147483770, here are decompositions:

  • 191 + 2147483579 = 2147483770
  • 227 + 2147483543 = 2147483770
  • 281 + 2147483489 = 2147483770
  • 293 + 2147483477 = 2147483770
  • 347 + 2147483423 = 2147483770
  • 521 + 2147483249 = 2147483770
  • 599 + 2147483171 = 2147483770
  • 647 + 2147483123 = 2147483770

Showing the first eight; more decompositions exist.
