Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538964, here are decompositions:

13 + 31538951 = 31538964
137 + 31538827 = 31538964
157 + 31538807 = 31538964
211 + 31538753 = 31538964
251 + 31538713 = 31538964
271 + 31538693 = 31538964
293 + 31538671 = 31538964
311 + 31538653 = 31538964

Showing the first eight; more decompositions exist.
