Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939844, here are decompositions:

5 + 939839 = 939844
53 + 939791 = 939844
71 + 939773 = 939844
107 + 939737 = 939844
131 + 939713 = 939844
137 + 939707 = 939844
167 + 939677 = 939844
233 + 939611 = 939844

Showing the first eight; more decompositions exist.
