Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537956, here are decompositions:

17 + 31537939 = 31537956
53 + 31537903 = 31537956
67 + 31537889 = 31537956
97 + 31537859 = 31537956
113 + 31537843 = 31537956
239 + 31537717 = 31537956
269 + 31537687 = 31537956
347 + 31537609 = 31537956

Showing the first eight; more decompositions exist.
