Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31575254, here are decompositions:

13 + 31575241 = 31575254
37 + 31575217 = 31575254
103 + 31575151 = 31575254
163 + 31575091 = 31575254
181 + 31575073 = 31575254
367 + 31574887 = 31575254
433 + 31574821 = 31575254
577 + 31574677 = 31575254

Showing the first eight; more decompositions exist.
