Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577112, here are decompositions:

29 + 31577083 = 31577112
31 + 31577081 = 31577112
41 + 31577071 = 31577112
59 + 31577053 = 31577112
103 + 31577009 = 31577112
163 + 31576949 = 31577112
181 + 31576931 = 31577112
211 + 31576901 = 31577112

Showing the first eight; more decompositions exist.
