Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630920, here are decompositions:

17 + 8630903 = 8630920
59 + 8630861 = 8630920
83 + 8630837 = 8630920
107 + 8630813 = 8630920
131 + 8630789 = 8630920
149 + 8630771 = 8630920
251 + 8630669 = 8630920
257 + 8630663 = 8630920

Showing the first eight; more decompositions exist.
