Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31575604, here are decompositions:

41 + 31575563 = 31575604
83 + 31575521 = 31575604
167 + 31575437 = 31575604
197 + 31575407 = 31575604
227 + 31575377 = 31575604
251 + 31575353 = 31575604
293 + 31575311 = 31575604
383 + 31575221 = 31575604

Showing the first eight; more decompositions exist.
