Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77618, here are decompositions:

7 + 77611 = 77618
31 + 77587 = 77618
61 + 77557 = 77618
67 + 77551 = 77618
97 + 77521 = 77618
109 + 77509 = 77618
127 + 77491 = 77618
139 + 77479 = 77618

Showing the first eight; more decompositions exist.
