Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77528, here are decompositions:

7 + 77521 = 77528
19 + 77509 = 77528
37 + 77491 = 77528
97 + 77431 = 77528
109 + 77419 = 77528
151 + 77377 = 77528
181 + 77347 = 77528
211 + 77317 = 77528

Showing the first eight; more decompositions exist.
