Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147499722, here are decompositions:

  • 19 + 2147499703 = 2147499722
  • 211 + 2147499511 = 2147499722
  • 241 + 2147499481 = 2147499722
  • 271 + 2147499451 = 2147499722
  • 331 + 2147499391 = 2147499722
  • 373 + 2147499349 = 2147499722
  • 439 + 2147499283 = 2147499722
  • 631 + 2147499091 = 2147499722

Showing the first eight; more decompositions exist.
