Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641458, here are decompositions:

5 + 8641453 = 8641458
29 + 8641429 = 8641458
37 + 8641421 = 8641458
97 + 8641361 = 8641458
107 + 8641351 = 8641458
109 + 8641349 = 8641458
127 + 8641331 = 8641458
131 + 8641327 = 8641458

Showing the first eight; more decompositions exist.
