Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577262, here are decompositions:

23 + 31577239 = 31577262
29 + 31577233 = 31577262
53 + 31577209 = 31577262
89 + 31577173 = 31577262
103 + 31577159 = 31577262
131 + 31577131 = 31577262
149 + 31577113 = 31577262
179 + 31577083 = 31577262

Showing the first eight; more decompositions exist.
