Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468576, here are decompositions:

3 + 31468573 = 31468576
5 + 31468571 = 31468576
17 + 31468559 = 31468576
23 + 31468553 = 31468576
47 + 31468529 = 31468576
53 + 31468523 = 31468576
59 + 31468517 = 31468576
173 + 31468403 = 31468576

Showing the first eight; more decompositions exist.
