Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64942, here are decompositions:

5 + 64937 = 64942
23 + 64919 = 64942
41 + 64901 = 64942
71 + 64871 = 64942
89 + 64853 = 64942
131 + 64811 = 64942
149 + 64793 = 64942
179 + 64763 = 64942

Showing the first eight; more decompositions exist.
