Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538014, here are decompositions:

17 + 31537997 = 31538014
191 + 31537823 = 31538014
293 + 31537721 = 31538014
383 + 31537631 = 31538014
467 + 31537547 = 31538014
701 + 31537313 = 31538014
743 + 31537271 = 31538014
863 + 31537151 = 31538014

Showing the first eight; more decompositions exist.
