Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597552, here are decompositions:

3 + 31597549 = 31597552
11 + 31597541 = 31597552
59 + 31597493 = 31597552
269 + 31597283 = 31597552
353 + 31597199 = 31597552
401 + 31597151 = 31597552
431 + 31597121 = 31597552
509 + 31597043 = 31597552

Showing the first eight; more decompositions exist.
