Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8610942, here are decompositions:

5 + 8610937 = 8610942
23 + 8610919 = 8610942
29 + 8610913 = 8610942
61 + 8610881 = 8610942
71 + 8610871 = 8610942
79 + 8610863 = 8610942
113 + 8610829 = 8610942
139 + 8610803 = 8610942

Showing the first eight; more decompositions exist.
