Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631416, here are decompositions:

37 + 8631379 = 8631416
43 + 8631373 = 8631416
97 + 8631319 = 8631416
109 + 8631307 = 8631416
139 + 8631277 = 8631416
223 + 8631193 = 8631416
307 + 8631109 = 8631416
379 + 8631037 = 8631416

Showing the first eight; more decompositions exist.
