Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66684, here are decompositions:

31 + 66653 = 66684
41 + 66643 = 66684
67 + 66617 = 66684
83 + 66601 = 66684
97 + 66587 = 66684
113 + 66571 = 66684
131 + 66553 = 66684
151 + 66533 = 66684

Showing the first eight; more decompositions exist.
