Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7918, here are decompositions:

11 + 7907 = 7918
17 + 7901 = 7918
41 + 7877 = 7918
89 + 7829 = 7918
101 + 7817 = 7918
191 + 7727 = 7918
227 + 7691 = 7918
269 + 7649 = 7918

Showing the first eight; more decompositions exist.
