Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534050, here are decompositions:

17 + 31534033 = 31534050
71 + 31533979 = 31534050
83 + 31533967 = 31534050
101 + 31533949 = 31534050
127 + 31533923 = 31534050
131 + 31533919 = 31534050
139 + 31533911 = 31534050
179 + 31533871 = 31534050

Showing the first eight; more decompositions exist.
