Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537504, here are decompositions:

23 + 31537481 = 31537504
71 + 31537433 = 31537504
113 + 31537391 = 31537504
191 + 31537313 = 31537504
197 + 31537307 = 31537504
233 + 31537271 = 31537504
281 + 31537223 = 31537504
353 + 31537151 = 31537504

Showing the first eight; more decompositions exist.
