Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66116, here are decompositions:

  • 7 + 66109 = 66116
  • 13 + 66103 = 66116
  • 79 + 66037 = 66116
  • 277 + 65839 = 66116
  • 307 + 65809 = 66116
  • 397 + 65719 = 66116
  • 409 + 65707 = 66116
  • 439 + 65677 = 66116

Showing the first eight; more decompositions exist.
