Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514700, here are decompositions:

11 + 31514689 = 31514700
13 + 31514687 = 31514700
29 + 31514671 = 31514700
37 + 31514663 = 31514700
47 + 31514653 = 31514700
59 + 31514641 = 31514700
71 + 31514629 = 31514700
73 + 31514627 = 31514700

Showing the first eight; more decompositions exist.
