Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627576, here are decompositions:

3 + 31627573 = 31627576
17 + 31627559 = 31627576
257 + 31627319 = 31627576
359 + 31627217 = 31627576
443 + 31627133 = 31627576
503 + 31627073 = 31627576
569 + 31627007 = 31627576
599 + 31626977 = 31627576

Showing the first eight; more decompositions exist.
