Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529056, here are decompositions:

3 + 31529053 = 31529056
59 + 31528997 = 31529056
89 + 31528967 = 31529056
233 + 31528823 = 31529056
359 + 31528697 = 31529056
443 + 31528613 = 31529056
509 + 31528547 = 31529056
557 + 31528499 = 31529056

Showing the first eight; more decompositions exist.
