Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31481952, here are decompositions:

13 + 31481939 = 31481952
31 + 31481921 = 31481952
41 + 31481911 = 31481952
53 + 31481899 = 31481952
101 + 31481851 = 31481952
109 + 31481843 = 31481952
199 + 31481753 = 31481952
239 + 31481713 = 31481952

Showing the first eight; more decompositions exist.
