Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667636, here are decompositions:

23 + 8667613 = 8667636
73 + 8667563 = 8667636
97 + 8667539 = 8667636
139 + 8667497 = 8667636
179 + 8667457 = 8667636
223 + 8667413 = 8667636
233 + 8667403 = 8667636
317 + 8667319 = 8667636

Showing the first eight; more decompositions exist.
