Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648420, here are decompositions:

7 + 8648413 = 8648420
31 + 8648389 = 8648420
73 + 8648347 = 8648420
97 + 8648323 = 8648420
103 + 8648317 = 8648420
181 + 8648239 = 8648420
199 + 8648221 = 8648420
229 + 8648191 = 8648420

Showing the first eight; more decompositions exist.
