Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939868, here are decompositions:

29 + 939839 = 939868
101 + 939767 = 939868
131 + 939737 = 939868
191 + 939677 = 939868
257 + 939611 = 939868
269 + 939599 = 939868
317 + 939551 = 939868
491 + 939377 = 939868

Showing the first eight; more decompositions exist.
