Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66672, here are decompositions:

19 + 66653 = 66672
29 + 66643 = 66672
43 + 66629 = 66672
71 + 66601 = 66672
79 + 66593 = 66672
101 + 66571 = 66672
103 + 66569 = 66672
131 + 66541 = 66672

Showing the first eight; more decompositions exist.
