Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646634, here are decompositions:

53 + 8646581 = 8646634
131 + 8646503 = 8646634
137 + 8646497 = 8646634
233 + 8646401 = 8646634
257 + 8646377 = 8646634
317 + 8646317 = 8646634
401 + 8646233 = 8646634
617 + 8646017 = 8646634

Showing the first eight; more decompositions exist.
