Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3700, here are decompositions:

3 + 3697 = 3700
23 + 3677 = 3700
29 + 3671 = 3700
41 + 3659 = 3700
83 + 3617 = 3700
107 + 3593 = 3700
167 + 3533 = 3700
173 + 3527 = 3700

Showing the first eight; more decompositions exist.
