Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577304, here are decompositions:

13 + 31577291 = 31577304
41 + 31577263 = 31577304
43 + 31577261 = 31577304
71 + 31577233 = 31577304
107 + 31577197 = 31577304
131 + 31577173 = 31577304
173 + 31577131 = 31577304
191 + 31577113 = 31577304

Showing the first eight; more decompositions exist.
