Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31575134, here are decompositions:

43 + 31575091 = 31575134
61 + 31575073 = 31575134
223 + 31574911 = 31575134
271 + 31574863 = 31575134
313 + 31574821 = 31575134
433 + 31574701 = 31575134
457 + 31574677 = 31575134
463 + 31574671 = 31575134

Showing the first eight; more decompositions exist.
