Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492840, here are decompositions:

  • 139 + 2147492701 = 2147492840
  • 307 + 2147492533 = 2147492840
  • 313 + 2147492527 = 2147492840
  • 349 + 2147492491 = 2147492840
  • 487 + 2147492353 = 2147492840
  • 523 + 2147492317 = 2147492840
  • 541 + 2147492299 = 2147492840
  • 601 + 2147492239 = 2147492840

Showing the first eight; more decompositions exist.
