Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574058, here are decompositions:

11 + 31574047 = 31574058
17 + 31574041 = 31574058
37 + 31574021 = 31574058
59 + 31573999 = 31574058
97 + 31573961 = 31574058
101 + 31573957 = 31574058
127 + 31573931 = 31574058
199 + 31573859 = 31574058

Showing the first eight; more decompositions exist.
