Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939100, here are decompositions:

11 + 939089 = 939100
89 + 939011 = 939100
131 + 938969 = 939100
137 + 938963 = 939100
179 + 938921 = 939100
257 + 938843 = 939100
269 + 938831 = 939100
293 + 938807 = 939100

Showing the first eight; more decompositions exist.
