Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681626, here are decompositions:

3 + 8681623 = 8681626
47 + 8681579 = 8681626
59 + 8681567 = 8681626
113 + 8681513 = 8681626
137 + 8681489 = 8681626
179 + 8681447 = 8681626
197 + 8681429 = 8681626
257 + 8681369 = 8681626

Showing the first eight; more decompositions exist.
