Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661776, here are decompositions:

7 + 8661769 = 8661776
43 + 8661733 = 8661776
73 + 8661703 = 8661776
103 + 8661673 = 8661776
199 + 8661577 = 8661776
223 + 8661553 = 8661776
307 + 8661469 = 8661776
337 + 8661439 = 8661776

Showing the first eight; more decompositions exist.
