Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718404, here are decompositions:

3 + 8718401 = 8718404
61 + 8718343 = 8718404
103 + 8718301 = 8718404
127 + 8718277 = 8718404
157 + 8718247 = 8718404
241 + 8718163 = 8718404
307 + 8718097 = 8718404
313 + 8718091 = 8718404

Showing the first eight; more decompositions exist.
