Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3778, here are decompositions:

11 + 3767 = 3778
17 + 3761 = 3778
59 + 3719 = 3778
101 + 3677 = 3778
107 + 3671 = 3778
197 + 3581 = 3778
239 + 3539 = 3778
251 + 3527 = 3778

Showing the first eight; more decompositions exist.
