Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661738, here are decompositions:

5 + 8661733 = 8661738
11 + 8661727 = 8661738
31 + 8661707 = 8661738
97 + 8661641 = 8661738
109 + 8661629 = 8661738
157 + 8661581 = 8661738
167 + 8661571 = 8661738
181 + 8661557 = 8661738

Showing the first eight; more decompositions exist.
