Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31575594, here are decompositions:

23 + 31575571 = 31575594
31 + 31575563 = 31575594
41 + 31575553 = 31575594
73 + 31575521 = 31575594
107 + 31575487 = 31575594
157 + 31575437 = 31575594
233 + 31575361 = 31575594
241 + 31575353 = 31575594

Showing the first eight; more decompositions exist.
