Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77436, here are decompositions:

5 + 77431 = 77436
17 + 77419 = 77436
19 + 77417 = 77436
53 + 77383 = 77436
59 + 77377 = 77436
67 + 77369 = 77436
89 + 77347 = 77436
97 + 77339 = 77436

Showing the first eight; more decompositions exist.
