Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623686, here are decompositions:

7 + 8623679 = 8623686
47 + 8623639 = 8623686
67 + 8623619 = 8623686
83 + 8623603 = 8623686
103 + 8623583 = 8623686
107 + 8623579 = 8623686
139 + 8623547 = 8623686
157 + 8623529 = 8623686

Showing the first eight; more decompositions exist.
