Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661042, here are decompositions:

41 + 8661001 = 8661042
59 + 8660983 = 8661042
73 + 8660969 = 8661042
109 + 8660933 = 8661042
113 + 8660929 = 8661042
151 + 8660891 = 8661042
179 + 8660863 = 8661042
223 + 8660819 = 8661042

Showing the first eight; more decompositions exist.
