Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661964, here are decompositions:

11 + 8661953 = 8661964
23 + 8661941 = 8661964
83 + 8661881 = 8661964
197 + 8661767 = 8661964
257 + 8661707 = 8661964
281 + 8661683 = 8661964
383 + 8661581 = 8661964
503 + 8661461 = 8661964

Showing the first eight; more decompositions exist.
