Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147584752, here are decompositions:

  • 59 + 2147584693 = 2147584752
  • 73 + 2147584679 = 2147584752
  • 83 + 2147584669 = 2147584752
  • 101 + 2147584651 = 2147584752
  • 149 + 2147584603 = 2147584752
  • 199 + 2147584553 = 2147584752
  • 223 + 2147584529 = 2147584752
  • 233 + 2147584519 = 2147584752

Showing the first eight; more decompositions exist.
