Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77630, here are decompositions:

13 + 77617 = 77630
19 + 77611 = 77630
43 + 77587 = 77630
61 + 77569 = 77630
67 + 77563 = 77630
73 + 77557 = 77630
79 + 77551 = 77630
103 + 77527 = 77630

Showing the first eight; more decompositions exist.
