Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630540, here are decompositions:

97 + 8630443 = 8630540
229 + 8630311 = 8630540
271 + 8630269 = 8630540
349 + 8630191 = 8630540
367 + 8630173 = 8630540
421 + 8630119 = 8630540
577 + 8629963 = 8630540
613 + 8629927 = 8630540

Showing the first eight; more decompositions exist.
