Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672586, here are decompositions:

23 + 8672563 = 8672586
47 + 8672539 = 8672586
59 + 8672527 = 8672586
67 + 8672519 = 8672586
73 + 8672513 = 8672586
103 + 8672483 = 8672586
157 + 8672429 = 8672586
163 + 8672423 = 8672586

Showing the first eight; more decompositions exist.
