Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31575526, here are decompositions:

5 + 31575521 = 31575526
89 + 31575437 = 31575526
149 + 31575377 = 31575526
173 + 31575353 = 31575526
293 + 31575233 = 31575526
419 + 31575107 = 31575526
467 + 31575059 = 31575526
557 + 31574969 = 31575526

Showing the first eight; more decompositions exist.
