Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3742, here are decompositions:

3 + 3739 = 3742
23 + 3719 = 3742
41 + 3701 = 3742
71 + 3671 = 3742
83 + 3659 = 3742
149 + 3593 = 3742
251 + 3491 = 3742
281 + 3461 = 3742

Showing the first eight; more decompositions exist.
