Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537794, here are decompositions:

47 + 31537747 = 31537794
53 + 31537741 = 31537794
73 + 31537721 = 31537794
103 + 31537691 = 31537794
107 + 31537687 = 31537794
163 + 31537631 = 31537794
191 + 31537603 = 31537794
251 + 31537543 = 31537794

Showing the first eight; more decompositions exist.
