Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 37990, here are decompositions:

3 + 37987 = 37990
23 + 37967 = 37990
83 + 37907 = 37990
101 + 37889 = 37990
137 + 37853 = 37990
179 + 37811 = 37990
191 + 37799 = 37990
347 + 37643 = 37990

Showing the first eight; more decompositions exist.
