Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 940900, here are decompositions:

11 + 940889 = 940900
29 + 940871 = 940900
47 + 940853 = 940900
71 + 940829 = 940900
83 + 940817 = 940900
113 + 940787 = 940900
167 + 940733 = 940900
173 + 940727 = 940900

Showing the first eight; more decompositions exist.
