Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31575926, here are decompositions:

3 + 31575923 = 31575926
97 + 31575829 = 31575926
103 + 31575823 = 31575926
127 + 31575799 = 31575926
157 + 31575769 = 31575926
199 + 31575727 = 31575926
229 + 31575697 = 31575926
373 + 31575553 = 31575926

Showing the first eight; more decompositions exist.
