Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631446, here are decompositions:

67 + 8631379 = 8631446
73 + 8631373 = 8631446
79 + 8631367 = 8631446
127 + 8631319 = 8631446
139 + 8631307 = 8631446
163 + 8631283 = 8631446
199 + 8631247 = 8631446
337 + 8631109 = 8631446

Showing the first eight; more decompositions exist.
