Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630990, here are decompositions:

7 + 8630983 = 8630990
19 + 8630971 = 8630990
61 + 8630929 = 8630990
139 + 8630851 = 8630990
157 + 8630833 = 8630990
211 + 8630779 = 8630990
241 + 8630749 = 8630990
307 + 8630683 = 8630990

Showing the first eight; more decompositions exist.
