Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450950, here are decompositions:

53 + 31450897 = 31450950
59 + 31450891 = 31450950
71 + 31450879 = 31450950
103 + 31450847 = 31450950
107 + 31450843 = 31450950
109 + 31450841 = 31450950
127 + 31450823 = 31450950
149 + 31450801 = 31450950

Showing the first eight; more decompositions exist.
