Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537738, here are decompositions:

17 + 31537721 = 31537738
47 + 31537691 = 31537738
107 + 31537631 = 31537738
179 + 31537559 = 31537738
191 + 31537547 = 31537738
257 + 31537481 = 31537738
269 + 31537469 = 31537738
347 + 31537391 = 31537738

Showing the first eight; more decompositions exist.
