Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631884, here are decompositions:

3 + 8631881 = 8631884
61 + 8631823 = 8631884
97 + 8631787 = 8631884
103 + 8631781 = 8631884
211 + 8631673 = 8631884
367 + 8631517 = 8631884
433 + 8631451 = 8631884
577 + 8631307 = 8631884

Showing the first eight; more decompositions exist.
