Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681628, here are decompositions:

5 + 8681623 = 8681628
41 + 8681587 = 8681628
61 + 8681567 = 8681628
79 + 8681549 = 8681628
89 + 8681539 = 8681628
139 + 8681489 = 8681628
181 + 8681447 = 8681628
199 + 8681429 = 8681628

Showing the first eight; more decompositions exist.
