Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537854, here are decompositions:

11 + 31537843 = 31537854
17 + 31537837 = 31537854
31 + 31537823 = 31537854
107 + 31537747 = 31537854
113 + 31537741 = 31537854
137 + 31537717 = 31537854
163 + 31537691 = 31537854
167 + 31537687 = 31537854

Showing the first eight; more decompositions exist.
