Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631802, here are decompositions:

59 + 8631743 = 8631802
89 + 8631713 = 8631802
173 + 8631629 = 8631802
191 + 8631611 = 8631802
233 + 8631569 = 8631802
269 + 8631533 = 8631802
401 + 8631401 = 8631802
461 + 8631341 = 8631802

Showing the first eight; more decompositions exist.
