Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577046, here are decompositions:

29 + 31577017 = 31577046
37 + 31577009 = 31577046
79 + 31576967 = 31577046
89 + 31576957 = 31577046
97 + 31576949 = 31577046
157 + 31576889 = 31577046
269 + 31576777 = 31577046
307 + 31576739 = 31577046

Showing the first eight; more decompositions exist.
