Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77538, here are decompositions:

11 + 77527 = 77538
17 + 77521 = 77538
29 + 77509 = 77538
47 + 77491 = 77538
59 + 77479 = 77538
61 + 77477 = 77538
67 + 77471 = 77538
107 + 77431 = 77538

Showing the first eight; more decompositions exist.
