Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661626, here are decompositions:

3 + 8661623 = 8661626
73 + 8661553 = 8661626
97 + 8661529 = 8661626
139 + 8661487 = 8661626
157 + 8661469 = 8661626
199 + 8661427 = 8661626
373 + 8661253 = 8661626
409 + 8661217 = 8661626

Showing the first eight; more decompositions exist.
