Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537734, here are decompositions:

13 + 31537721 = 31537734
17 + 31537717 = 31537734
43 + 31537691 = 31537734
47 + 31537687 = 31537734
103 + 31537631 = 31537734
131 + 31537603 = 31537734
191 + 31537543 = 31537734
227 + 31537507 = 31537734

Showing the first eight; more decompositions exist.
