Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38906, here are decompositions:

3 + 38903 = 38906
67 + 38839 = 38906
73 + 38833 = 38906
103 + 38803 = 38906
139 + 38767 = 38906
157 + 38749 = 38906
193 + 38713 = 38906
199 + 38707 = 38906

Showing the first eight; more decompositions exist.
