Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630842, here are decompositions:

5 + 8630837 = 8630842
29 + 8630813 = 8630842
53 + 8630789 = 8630842
71 + 8630771 = 8630842
83 + 8630759 = 8630842
173 + 8630669 = 8630842
179 + 8630663 = 8630842
251 + 8630591 = 8630842

Showing the first eight; more decompositions exist.
