Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577336, here are decompositions:

13 + 31577323 = 31577336
67 + 31577269 = 31577336
73 + 31577263 = 31577336
97 + 31577239 = 31577336
103 + 31577233 = 31577336
127 + 31577209 = 31577336
139 + 31577197 = 31577336
163 + 31577173 = 31577336

Showing the first eight; more decompositions exist.
