Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537756, here are decompositions:

197 + 31537559 = 31537756
347 + 31537409 = 31537756
443 + 31537313 = 31537756
449 + 31537307 = 31537756
659 + 31537097 = 31537756
773 + 31536983 = 31537756
797 + 31536959 = 31537756
839 + 31536917 = 31537756

Showing the first eight; more decompositions exist.
