Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537826, here are decompositions:

3 + 31537823 = 31537826
79 + 31537747 = 31537826
109 + 31537717 = 31537826
139 + 31537687 = 31537826
223 + 31537603 = 31537826
283 + 31537543 = 31537826
349 + 31537477 = 31537826
487 + 31537339 = 31537826

Showing the first eight; more decompositions exist.
