Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470584, here are decompositions:

3 + 31470581 = 31470584
37 + 31470547 = 31470584
367 + 31470217 = 31470584
433 + 31470151 = 31470584
487 + 31470097 = 31470584
547 + 31470037 = 31470584
571 + 31470013 = 31470584
631 + 31469953 = 31470584

Showing the first eight; more decompositions exist.
