Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537252, here are decompositions:

23 + 31537229 = 31537252
29 + 31537223 = 31537252
101 + 31537151 = 31537252
251 + 31537001 = 31537252
269 + 31536983 = 31537252
293 + 31536959 = 31537252
389 + 31536863 = 31537252
431 + 31536821 = 31537252

Showing the first eight; more decompositions exist.
