Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66042, here are decompositions:

5 + 66037 = 66042
13 + 66029 = 66042
59 + 65983 = 66042
61 + 65981 = 66042
79 + 65963 = 66042
113 + 65929 = 66042
191 + 65851 = 66042
199 + 65843 = 66042

Showing the first eight; more decompositions exist.
