Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644634, here are decompositions:

127 + 8644507 = 8644634
157 + 8644477 = 8644634
181 + 8644453 = 8644634
307 + 8644327 = 8644634
373 + 8644261 = 8644634
421 + 8644213 = 8644634
463 + 8644171 = 8644634
487 + 8644147 = 8644634

Showing the first eight; more decompositions exist.
