Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77530, here are decompositions:

3 + 77527 = 77530
17 + 77513 = 77530
41 + 77489 = 77530
53 + 77477 = 77530
59 + 77471 = 77530
83 + 77447 = 77530
113 + 77417 = 77530
179 + 77351 = 77530

Showing the first eight; more decompositions exist.
