Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567058, here are decompositions:

79 + 31566979 = 31567058
139 + 31566919 = 31567058
157 + 31566901 = 31567058
241 + 31566817 = 31567058
349 + 31566709 = 31567058
499 + 31566559 = 31567058
541 + 31566517 = 31567058
571 + 31566487 = 31567058

Showing the first eight; more decompositions exist.
