Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577196, here are decompositions:

23 + 31577173 = 31577196
37 + 31577159 = 31577196
67 + 31577129 = 31577196
83 + 31577113 = 31577196
113 + 31577083 = 31577196
139 + 31577057 = 31577196
179 + 31577017 = 31577196
229 + 31576967 = 31577196

Showing the first eight; more decompositions exist.
