Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77712, here are decompositions:

13 + 77699 = 77712
23 + 77689 = 77712
31 + 77681 = 77712
53 + 77659 = 77712
71 + 77641 = 77712
101 + 77611 = 77712
139 + 77573 = 77712
149 + 77563 = 77712

Showing the first eight; more decompositions exist.
