Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537724, here are decompositions:

3 + 31537721 = 31537724
7 + 31537717 = 31537724
37 + 31537687 = 31537724
151 + 31537573 = 31537724
181 + 31537543 = 31537724
397 + 31537327 = 31537724
457 + 31537267 = 31537724
523 + 31537201 = 31537724

Showing the first eight; more decompositions exist.
