Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468582, here are decompositions:

11 + 31468571 = 31468582
23 + 31468559 = 31468582
29 + 31468553 = 31468582
53 + 31468529 = 31468582
59 + 31468523 = 31468582
71 + 31468511 = 31468582
83 + 31468499 = 31468582
179 + 31468403 = 31468582

Showing the first eight; more decompositions exist.
