Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147584830, here are decompositions:

  • 19 + 2147584811 = 2147584830
  • 23 + 2147584807 = 2147584830
  • 137 + 2147584693 = 2147584830
  • 151 + 2147584679 = 2147584830
  • 173 + 2147584657 = 2147584830
  • 179 + 2147584651 = 2147584830
  • 227 + 2147584603 = 2147584830
  • 233 + 2147584597 = 2147584830

Showing the first eight; more decompositions exist.
