Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 940218, here are decompositions:

17 + 940201 = 940218
29 + 940189 = 940218
61 + 940157 = 940218
131 + 940087 = 940218
151 + 940067 = 940218
199 + 940019 = 940218
229 + 939989 = 940218
317 + 939901 = 940218

Showing the first eight; more decompositions exist.
