Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005618, here are decompositions:

37 + 1005581 = 1005618
67 + 1005551 = 1005618
137 + 1005481 = 1005618
151 + 1005467 = 1005618
179 + 1005439 = 1005618
181 + 1005437 = 1005618
191 + 1005427 = 1005618
227 + 1005391 = 1005618

Showing the first eight; more decompositions exist.
