Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939970, here are decompositions:

47 + 939923 = 939970
89 + 939881 = 939970
131 + 939839 = 939970
179 + 939791 = 939970
197 + 939773 = 939970
233 + 939737 = 939970
257 + 939713 = 939970
263 + 939707 = 939970

Showing the first eight; more decompositions exist.
