Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65442, here are decompositions:

5 + 65437 = 65442
19 + 65423 = 65442
23 + 65419 = 65442
29 + 65413 = 65442
61 + 65381 = 65442
71 + 65371 = 65442
89 + 65353 = 65442
149 + 65293 = 65442

Showing the first eight; more decompositions exist.
