Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681422, here are decompositions:

53 + 8681369 = 8681422
59 + 8681363 = 8681422
131 + 8681291 = 8681422
179 + 8681243 = 8681422
263 + 8681159 = 8681422
293 + 8681129 = 8681422
311 + 8681111 = 8681422
401 + 8681021 = 8681422

Showing the first eight; more decompositions exist.
