Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77518, here are decompositions:

5 + 77513 = 77518
29 + 77489 = 77518
41 + 77477 = 77518
47 + 77471 = 77518
71 + 77447 = 77518
101 + 77417 = 77518
149 + 77369 = 77518
167 + 77351 = 77518

Showing the first eight; more decompositions exist.
