Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637066, here are decompositions:

5 + 8637061 = 8637066
7 + 8637059 = 8637066
13 + 8637053 = 8637066
59 + 8637007 = 8637066
79 + 8636987 = 8637066
107 + 8636959 = 8637066
149 + 8636917 = 8637066
157 + 8636909 = 8637066

Showing the first eight; more decompositions exist.
