Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76618, here are decompositions:

11 + 76607 = 76618
107 + 76511 = 76618
131 + 76487 = 76618
137 + 76481 = 76618
197 + 76421 = 76618
239 + 76379 = 76618
251 + 76367 = 76618
359 + 76259 = 76618

Showing the first eight; more decompositions exist.
