Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718248, here are decompositions:

31 + 8718217 = 8718248
139 + 8718109 = 8718248
151 + 8718097 = 8718248
157 + 8718091 = 8718248
241 + 8718007 = 8718248
367 + 8717881 = 8718248
379 + 8717869 = 8718248
439 + 8717809 = 8718248

Showing the first eight; more decompositions exist.
