Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644488, here are decompositions:

11 + 8644477 = 8644488
31 + 8644457 = 8644488
37 + 8644451 = 8644488
157 + 8644331 = 8644488
227 + 8644261 = 8644488
257 + 8644231 = 8644488
317 + 8644171 = 8644488
331 + 8644157 = 8644488

Showing the first eight; more decompositions exist.
