Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615942, here are decompositions:

61 + 8615881 = 8615942
109 + 8615833 = 8615942
151 + 8615791 = 8615942
193 + 8615749 = 8615942
463 + 8615479 = 8615942
619 + 8615323 = 8615942
859 + 8615083 = 8615942
991 + 8614951 = 8615942

Showing the first eight; more decompositions exist.
