Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492678, here are decompositions:

  • 7 + 2147492671 = 2147492678
  • 127 + 2147492551 = 2147492678
  • 139 + 2147492539 = 2147492678
  • 151 + 2147492527 = 2147492678
  • 157 + 2147492521 = 2147492678
  • 307 + 2147492371 = 2147492678
  • 349 + 2147492329 = 2147492678
  • 379 + 2147492299 = 2147492678

Showing the first eight; more decompositions exist.
