Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577106, here are decompositions:

23 + 31577083 = 31577106
53 + 31577053 = 31577106
89 + 31577017 = 31577106
97 + 31577009 = 31577106
139 + 31576967 = 31577106
149 + 31576957 = 31577106
157 + 31576949 = 31577106
263 + 31576843 = 31577106

Showing the first eight; more decompositions exist.
