Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630240, here are decompositions:

61 + 8630179 = 8630240
67 + 8630173 = 8630240
127 + 8630113 = 8630240
211 + 8630029 = 8630240
277 + 8629963 = 8630240
313 + 8629927 = 8630240
331 + 8629909 = 8630240
349 + 8629891 = 8630240

Showing the first eight; more decompositions exist.
