Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38900, here are decompositions:

61 + 38839 = 38900
67 + 38833 = 38900
79 + 38821 = 38900
97 + 38803 = 38900
109 + 38791 = 38900
151 + 38749 = 38900
163 + 38737 = 38900
193 + 38707 = 38900

Showing the first eight; more decompositions exist.
