Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577088, here are decompositions:

5 + 31577083 = 31577088
7 + 31577081 = 31577088
17 + 31577071 = 31577088
31 + 31577057 = 31577088
71 + 31577017 = 31577088
79 + 31577009 = 31577088
97 + 31576991 = 31577088
131 + 31576957 = 31577088

Showing the first eight; more decompositions exist.
