Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631038, here are decompositions:

37 + 8631001 = 8631038
67 + 8630971 = 8631038
109 + 8630929 = 8631038
139 + 8630899 = 8631038
181 + 8630857 = 8631038
397 + 8630641 = 8631038
439 + 8630599 = 8631038
547 + 8630491 = 8631038

Showing the first eight; more decompositions exist.
