Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77672, here are decompositions:

13 + 77659 = 77672
31 + 77641 = 77672
61 + 77611 = 77672
103 + 77569 = 77672
109 + 77563 = 77672
151 + 77521 = 77672
163 + 77509 = 77672
181 + 77491 = 77672

Showing the first eight; more decompositions exist.
