Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576456, here are decompositions:

3 + 31576453 = 31576456
17 + 31576439 = 31576456
29 + 31576427 = 31576456
47 + 31576409 = 31576456
53 + 31576403 = 31576456
83 + 31576373 = 31576456
89 + 31576367 = 31576456
167 + 31576289 = 31576456

Showing the first eight; more decompositions exist.
