Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661494, here are decompositions:

3 + 8661491 = 8661494
7 + 8661487 = 8661494
67 + 8661427 = 8661494
241 + 8661253 = 8661494
271 + 8661223 = 8661494
277 + 8661217 = 8661494
313 + 8661181 = 8661494
433 + 8661061 = 8661494

Showing the first eight; more decompositions exist.
