Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472716, here are decompositions:

17 + 31472699 = 31472716
47 + 31472669 = 31472716
53 + 31472663 = 31472716
83 + 31472633 = 31472716
179 + 31472537 = 31472716
227 + 31472489 = 31472716
557 + 31472159 = 31472716
563 + 31472153 = 31472716

Showing the first eight; more decompositions exist.
