Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939778, here are decompositions:

5 + 939773 = 939778
11 + 939767 = 939778
29 + 939749 = 939778
41 + 939737 = 939778
71 + 939707 = 939778
101 + 939677 = 939778
167 + 939611 = 939778
179 + 939599 = 939778

Showing the first eight; more decompositions exist.
