Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718158, here are decompositions:

61 + 8718097 = 8718158
67 + 8718091 = 8718158
151 + 8718007 = 8718158
199 + 8717959 = 8718158
277 + 8717881 = 8718158
349 + 8717809 = 8718158
367 + 8717791 = 8718158
409 + 8717749 = 8718158

Showing the first eight; more decompositions exist.
