Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537754, here are decompositions:

7 + 31537747 = 31537754
13 + 31537741 = 31537754
37 + 31537717 = 31537754
67 + 31537687 = 31537754
151 + 31537603 = 31537754
163 + 31537591 = 31537754
181 + 31537573 = 31537754
211 + 31537543 = 31537754

Showing the first eight; more decompositions exist.
