Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661248, here are decompositions:

7 + 8661241 = 8661248
31 + 8661217 = 8661248
67 + 8661181 = 8661248
199 + 8661049 = 8661248
577 + 8660671 = 8661248
709 + 8660539 = 8661248
787 + 8660461 = 8661248
811 + 8660437 = 8661248

Showing the first eight; more decompositions exist.
