Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537564, here are decompositions:

5 + 31537559 = 31537564
17 + 31537547 = 31537564
83 + 31537481 = 31537564
131 + 31537433 = 31537564
173 + 31537391 = 31537564
251 + 31537313 = 31537564
257 + 31537307 = 31537564
293 + 31537271 = 31537564

Showing the first eight; more decompositions exist.
