Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471552, here are decompositions:

3 + 31471549 = 31471552
29 + 31471523 = 31471552
41 + 31471511 = 31471552
71 + 31471481 = 31471552
83 + 31471469 = 31471552
113 + 31471439 = 31471552
179 + 31471373 = 31471552
191 + 31471361 = 31471552

Showing the first eight; more decompositions exist.
