Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939890, here are decompositions:

19 + 939871 = 939890
37 + 939853 = 939890
43 + 939847 = 939890
67 + 939823 = 939890
97 + 939793 = 939890
151 + 939739 = 939890
229 + 939661 = 939890
241 + 939649 = 939890

Showing the first eight; more decompositions exist.
