Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631452, here are decompositions:

61 + 8631391 = 8631452
73 + 8631379 = 8631452
79 + 8631373 = 8631452
223 + 8631229 = 8631452
523 + 8630929 = 8631452
601 + 8630851 = 8631452
619 + 8630833 = 8631452
631 + 8630821 = 8631452

Showing the first eight; more decompositions exist.
