Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449652, here are decompositions:

5 + 31449647 = 31449652
23 + 31449629 = 31449652
41 + 31449611 = 31449652
71 + 31449581 = 31449652
83 + 31449569 = 31449652
173 + 31449479 = 31449652
251 + 31449401 = 31449652
293 + 31449359 = 31449652

Showing the first eight; more decompositions exist.
