Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8650420, here are decompositions:

11 + 8650409 = 8650420
29 + 8650391 = 8650420
59 + 8650361 = 8650420
101 + 8650319 = 8650420
113 + 8650307 = 8650420
137 + 8650283 = 8650420
167 + 8650253 = 8650420
197 + 8650223 = 8650420

Showing the first eight; more decompositions exist.
