Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3698, here are decompositions:

7 + 3691 = 3698
61 + 3637 = 3698
67 + 3631 = 3698
127 + 3571 = 3698
139 + 3559 = 3698
151 + 3547 = 3698
157 + 3541 = 3698
181 + 3517 = 3698

Showing the first eight; more decompositions exist.
