Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100938, here are decompositions:

7 + 100931 = 100938
11 + 100927 = 100938
31 + 100907 = 100938
109 + 100829 = 100938
127 + 100811 = 100938
137 + 100801 = 100938
139 + 100799 = 100938
151 + 100787 = 100938

Showing the first eight; more decompositions exist.
