Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77508, here are decompositions:

17 + 77491 = 77508
19 + 77489 = 77508
29 + 77479 = 77508
31 + 77477 = 77508
37 + 77471 = 77508
61 + 77447 = 77508
89 + 77419 = 77508
131 + 77377 = 77508

Showing the first eight; more decompositions exist.
