Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537716, here are decompositions:

29 + 31537687 = 31537716
107 + 31537609 = 31537716
113 + 31537603 = 31537716
157 + 31537559 = 31537716
173 + 31537543 = 31537716
239 + 31537477 = 31537716
283 + 31537433 = 31537716
307 + 31537409 = 31537716

Showing the first eight; more decompositions exist.
