Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717942, here are decompositions:

3 + 8717939 = 8717942
61 + 8717881 = 8717942
73 + 8717869 = 8717942
139 + 8717803 = 8717942
151 + 8717791 = 8717942
193 + 8717749 = 8717942
199 + 8717743 = 8717942
379 + 8717563 = 8717942

Showing the first eight; more decompositions exist.
