Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 37720, here are decompositions:

3 + 37717 = 37720
29 + 37691 = 37720
71 + 37649 = 37720
101 + 37619 = 37720
113 + 37607 = 37720
131 + 37589 = 37720
149 + 37571 = 37720
173 + 37547 = 37720

Showing the first eight; more decompositions exist.
