Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452956, here are decompositions:

13 + 31452943 = 31452956
97 + 31452859 = 31452956
127 + 31452829 = 31452956
163 + 31452793 = 31452956
193 + 31452763 = 31452956
229 + 31452727 = 31452956
307 + 31452649 = 31452956
349 + 31452607 = 31452956

Showing the first eight; more decompositions exist.
