Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576416, here are decompositions:

5 + 31576411 = 31576416
7 + 31576409 = 31576416
13 + 31576403 = 31576416
43 + 31576373 = 31576416
127 + 31576289 = 31576416
149 + 31576267 = 31576416
163 + 31576253 = 31576416
197 + 31576219 = 31576416

Showing the first eight; more decompositions exist.
