Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19616, here are decompositions:

  • 7 + 19609 = 19616
  • 13 + 19603 = 19616
  • 19 + 19597 = 19616
  • 73 + 19543 = 19616
  • 109 + 19507 = 19616
  • 127 + 19489 = 19616
  • 139 + 19477 = 19616
  • 193 + 19423 = 19616

Showing the first eight; more decompositions exist.
