Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534950, here are decompositions:

37 + 31534913 = 31534950
71 + 31534879 = 31534950
79 + 31534871 = 31534950
131 + 31534819 = 31534950
149 + 31534801 = 31534950
151 + 31534799 = 31534950
163 + 31534787 = 31534950
193 + 31534757 = 31534950

Showing the first eight; more decompositions exist.
