Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68618, here are decompositions:

7 + 68611 = 68618
37 + 68581 = 68618
79 + 68539 = 68618
97 + 68521 = 68618
127 + 68491 = 68618
181 + 68437 = 68618
229 + 68389 = 68618
307 + 68311 = 68618

Showing the first eight; more decompositions exist.
