Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668038, here are decompositions:

7 + 8668031 = 8668038
37 + 8668001 = 8668038
59 + 8667979 = 8668038
89 + 8667949 = 8668038
107 + 8667931 = 8668038
109 + 8667929 = 8668038
131 + 8667907 = 8668038
139 + 8667899 = 8668038

Showing the first eight; more decompositions exist.
