Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64042, here are decompositions:

5 + 64037 = 64042
23 + 64019 = 64042
29 + 64013 = 64042
113 + 63929 = 64042
179 + 63863 = 64042
233 + 63809 = 64042
239 + 63803 = 64042
269 + 63773 = 64042

Showing the first eight; more decompositions exist.
