Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737218, here are decompositions:

19 + 8737199 = 8737218
41 + 8737177 = 8737218
79 + 8737139 = 8737218
89 + 8737129 = 8737218
101 + 8737117 = 8737218
107 + 8737111 = 8737218
151 + 8737067 = 8737218
157 + 8737061 = 8737218

Showing the first eight; more decompositions exist.
