Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567950, here are decompositions:

19 + 31567931 = 31567950
67 + 31567883 = 31567950
101 + 31567849 = 31567950
131 + 31567819 = 31567950
137 + 31567813 = 31567950
181 + 31567769 = 31567950
233 + 31567717 = 31567950
241 + 31567709 = 31567950

Showing the first eight; more decompositions exist.
