Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574456, here are decompositions:

3 + 31574453 = 31574456
7 + 31574449 = 31574456
13 + 31574443 = 31574456
19 + 31574437 = 31574456
37 + 31574419 = 31574456
127 + 31574329 = 31574456
223 + 31574233 = 31574456
283 + 31574173 = 31574456

Showing the first eight; more decompositions exist.
