Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501050, here are decompositions:

11 + 31501039 = 31501050
13 + 31501037 = 31501050
41 + 31501009 = 31501050
71 + 31500979 = 31501050
73 + 31500977 = 31501050
83 + 31500967 = 31501050
103 + 31500947 = 31501050
109 + 31500941 = 31501050

Showing the first eight; more decompositions exist.
