Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631788, here are decompositions:

7 + 8631781 = 8631788
19 + 8631769 = 8631788
271 + 8631517 = 8631788
337 + 8631451 = 8631788
397 + 8631391 = 8631788
409 + 8631379 = 8631788
421 + 8631367 = 8631788
457 + 8631331 = 8631788

Showing the first eight; more decompositions exist.
