Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147499818, here are decompositions:

  • 241 + 2147499577 = 2147499818
  • 271 + 2147499547 = 2147499818
  • 307 + 2147499511 = 2147499818
  • 337 + 2147499481 = 2147499818
  • 367 + 2147499451 = 2147499818
  • 439 + 2147499379 = 2147499818
  • 577 + 2147499241 = 2147499818
  • 601 + 2147499217 = 2147499818

Showing the first eight; more decompositions exist.
