Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577064, here are decompositions:

7 + 31577057 = 31577064
11 + 31577053 = 31577064
47 + 31577017 = 31577064
73 + 31576991 = 31577064
97 + 31576967 = 31577064
107 + 31576957 = 31577064
163 + 31576901 = 31577064
173 + 31576891 = 31577064

Showing the first eight; more decompositions exist.
