Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681652, here are decompositions:

13 + 8681639 = 8681652
29 + 8681623 = 8681652
73 + 8681579 = 8681652
103 + 8681549 = 8681652
113 + 8681539 = 8681652
139 + 8681513 = 8681652
149 + 8681503 = 8681652
163 + 8681489 = 8681652

Showing the first eight; more decompositions exist.
