Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534938, here are decompositions:

59 + 31534879 = 31534938
67 + 31534871 = 31534938
107 + 31534831 = 31534938
137 + 31534801 = 31534938
139 + 31534799 = 31534938
151 + 31534787 = 31534938
181 + 31534757 = 31534938
199 + 31534739 = 31534938

Showing the first eight; more decompositions exist.
