Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147499546, here are decompositions:

  • 7 + 2147499539 = 2147499546
  • 13 + 2147499533 = 2147499546
  • 37 + 2147499509 = 2147499546
  • 67 + 2147499479 = 2147499546
  • 89 + 2147499457 = 2147499546
  • 109 + 2147499437 = 2147499546
  • 113 + 2147499433 = 2147499546
  • 167 + 2147499379 = 2147499546

Showing the first eight; more decompositions exist.
