Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 60666, here are decompositions:

5 + 60661 = 60666
7 + 60659 = 60666
17 + 60649 = 60666
19 + 60647 = 60666
29 + 60637 = 60666
43 + 60623 = 60666
59 + 60607 = 60666
127 + 60539 = 60666

Showing the first eight; more decompositions exist.
