Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737138, here are decompositions:

41 + 8737097 = 8737138
71 + 8737067 = 8737138
89 + 8737049 = 8737138
149 + 8736989 = 8737138
227 + 8736911 = 8737138
239 + 8736899 = 8737138
257 + 8736881 = 8737138
419 + 8736719 = 8737138

Showing the first eight; more decompositions exist.
