Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465932, here are decompositions:

41 + 31465891 = 31465932
53 + 31465879 = 31465932
83 + 31465849 = 31465932
101 + 31465831 = 31465932
103 + 31465829 = 31465932
131 + 31465801 = 31465932
151 + 31465781 = 31465932
191 + 31465741 = 31465932

Showing the first eight; more decompositions exist.
