Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8650458, here are decompositions:

7 + 8650451 = 8650458
29 + 8650429 = 8650458
67 + 8650391 = 8650458
97 + 8650361 = 8650458
137 + 8650321 = 8650458
139 + 8650319 = 8650458
149 + 8650309 = 8650458
151 + 8650307 = 8650458

Showing the first eight; more decompositions exist.
