Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8632420, here are decompositions:

29 + 8632391 = 8632420
53 + 8632367 = 8632420
59 + 8632361 = 8632420
107 + 8632313 = 8632420
197 + 8632223 = 8632420
233 + 8632187 = 8632420
263 + 8632157 = 8632420
281 + 8632139 = 8632420

Showing the first eight; more decompositions exist.
