Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630242, here are decompositions:

3 + 8630239 = 8630242
11 + 8630231 = 8630242
41 + 8630201 = 8630242
83 + 8630159 = 8630242
239 + 8630003 = 8630242
281 + 8629961 = 8630242
293 + 8629949 = 8630242
353 + 8629889 = 8630242

Showing the first eight; more decompositions exist.
