Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630886, here are decompositions:

29 + 8630857 = 8630886
53 + 8630833 = 8630886
73 + 8630813 = 8630886
97 + 8630789 = 8630886
107 + 8630779 = 8630886
127 + 8630759 = 8630886
137 + 8630749 = 8630886
149 + 8630737 = 8630886

Showing the first eight; more decompositions exist.
