Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471584, here are decompositions:

5 + 31471579 = 31471584
7 + 31471577 = 31471584
61 + 31471523 = 31471584
73 + 31471511 = 31471584
103 + 31471481 = 31471584
127 + 31471457 = 31471584
173 + 31471411 = 31471584
197 + 31471387 = 31471584

Showing the first eight; more decompositions exist.
