Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577346, here are decompositions:

23 + 31577323 = 31577346
83 + 31577263 = 31577346
107 + 31577239 = 31577346
113 + 31577233 = 31577346
137 + 31577209 = 31577346
149 + 31577197 = 31577346
173 + 31577173 = 31577346
233 + 31577113 = 31577346

Showing the first eight; more decompositions exist.
