Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 949990, here are decompositions:

3 + 949987 = 949990
11 + 949979 = 949990
17 + 949973 = 949990
23 + 949967 = 949990
29 + 949961 = 949990
53 + 949937 = 949990
59 + 949931 = 949990
101 + 949889 = 949990

Showing the first eight; more decompositions exist.
