Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537914, here are decompositions:

11 + 31537903 = 31537914
43 + 31537871 = 31537914
53 + 31537861 = 31537914
71 + 31537843 = 31537914
167 + 31537747 = 31537914
173 + 31537741 = 31537914
193 + 31537721 = 31537914
197 + 31537717 = 31537914

Showing the first eight; more decompositions exist.
