Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661422, here are decompositions:

181 + 8661241 = 8661422
199 + 8661223 = 8661422
229 + 8661193 = 8661422
241 + 8661181 = 8661422
373 + 8661049 = 8661422
379 + 8661043 = 8661422
421 + 8661001 = 8661422
439 + 8660983 = 8661422

Showing the first eight; more decompositions exist.
