Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631722, here are decompositions:

223 + 8631499 = 8631722
271 + 8631451 = 8631722
331 + 8631391 = 8631722
349 + 8631373 = 8631722
439 + 8631283 = 8631722
523 + 8631199 = 8631722
571 + 8631151 = 8631722
613 + 8631109 = 8631722

Showing the first eight; more decompositions exist.
