Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31575226, here are decompositions:

5 + 31575221 = 31575226
167 + 31575059 = 31575226
227 + 31574999 = 31575226
257 + 31574969 = 31575226
479 + 31574747 = 31575226
503 + 31574723 = 31575226
569 + 31574657 = 31575226
587 + 31574639 = 31575226

Showing the first eight; more decompositions exist.
