Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3518, here are decompositions:

7 + 3511 = 3518
19 + 3499 = 3518
61 + 3457 = 3518
127 + 3391 = 3518
157 + 3361 = 3518
199 + 3319 = 3518
211 + 3307 = 3518
331 + 3187 = 3518

Showing the first eight; more decompositions exist.
