Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8685740, here are decompositions:

3 + 8685737 = 8685740
31 + 8685709 = 8685740
73 + 8685667 = 8685740
79 + 8685661 = 8685740
103 + 8685637 = 8685740
109 + 8685631 = 8685740
139 + 8685601 = 8685740
157 + 8685583 = 8685740

Showing the first eight; more decompositions exist.
