Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616042, here are decompositions:

5 + 8616037 = 8616042
13 + 8616029 = 8616042
23 + 8616019 = 8616042
31 + 8616011 = 8616042
53 + 8615989 = 8616042
59 + 8615983 = 8616042
79 + 8615963 = 8616042
101 + 8615941 = 8616042

Showing the first eight; more decompositions exist.
