Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939912, here are decompositions:

11 + 939901 = 939912
31 + 939881 = 939912
41 + 939871 = 939912
59 + 939853 = 939912
73 + 939839 = 939912
89 + 939823 = 939912
139 + 939773 = 939912
163 + 939749 = 939912

Showing the first eight; more decompositions exist.
