Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3818, here are decompositions:

79 + 3739 = 3818
109 + 3709 = 3818
127 + 3691 = 3818
181 + 3637 = 3818
211 + 3607 = 3818
271 + 3547 = 3818
277 + 3541 = 3818
307 + 3511 = 3818

Showing the first eight; more decompositions exist.
