Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537524, here are decompositions:

17 + 31537507 = 31537524
43 + 31537481 = 31537524
47 + 31537477 = 31537524
197 + 31537327 = 31537524
211 + 31537313 = 31537524
251 + 31537273 = 31537524
257 + 31537267 = 31537524
281 + 31537243 = 31537524

Showing the first eight; more decompositions exist.
