Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501932, here are decompositions:

19 + 31501913 = 31501932
53 + 31501879 = 31501932
71 + 31501861 = 31501932
83 + 31501849 = 31501932
101 + 31501831 = 31501932
109 + 31501823 = 31501932
113 + 31501819 = 31501932
151 + 31501781 = 31501932

Showing the first eight; more decompositions exist.
