Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577058, here are decompositions:

5 + 31577053 = 31577058
41 + 31577017 = 31577058
67 + 31576991 = 31577058
101 + 31576957 = 31577058
109 + 31576949 = 31577058
127 + 31576931 = 31577058
157 + 31576901 = 31577058
167 + 31576891 = 31577058

Showing the first eight; more decompositions exist.
