Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737188, here are decompositions:

11 + 8737177 = 8737188
59 + 8737129 = 8737188
71 + 8737117 = 8737188
127 + 8737061 = 8737188
139 + 8737049 = 8737188
149 + 8737039 = 8737188
167 + 8737021 = 8737188
199 + 8736989 = 8737188

Showing the first eight; more decompositions exist.
