Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499050, here are decompositions:

17 + 31499033 = 31499050
29 + 31499021 = 31499050
47 + 31499003 = 31499050
59 + 31498991 = 31499050
83 + 31498967 = 31499050
101 + 31498949 = 31499050
137 + 31498913 = 31499050
197 + 31498853 = 31499050

Showing the first eight; more decompositions exist.
