Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537606, here are decompositions:

3 + 31537603 = 31537606
47 + 31537559 = 31537606
59 + 31537547 = 31537606
137 + 31537469 = 31537606
173 + 31537433 = 31537606
197 + 31537409 = 31537606
293 + 31537313 = 31537606
383 + 31537223 = 31537606

Showing the first eight; more decompositions exist.
