Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77442, here are decompositions:

11 + 77431 = 77442
23 + 77419 = 77442
59 + 77383 = 77442
73 + 77369 = 77442
83 + 77359 = 77442
103 + 77339 = 77442
151 + 77291 = 77442
163 + 77279 = 77442

Showing the first eight; more decompositions exist.
