Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644458, here are decompositions:

5 + 8644453 = 8644458
7 + 8644451 = 8644458
19 + 8644439 = 8644458
61 + 8644397 = 8644458
127 + 8644331 = 8644458
131 + 8644327 = 8644458
157 + 8644301 = 8644458
197 + 8644261 = 8644458

Showing the first eight; more decompositions exist.
