Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468558, here are decompositions:

5 + 31468553 = 31468558
29 + 31468529 = 31468558
41 + 31468517 = 31468558
47 + 31468511 = 31468558
59 + 31468499 = 31468558
167 + 31468391 = 31468558
227 + 31468331 = 31468558
239 + 31468319 = 31468558

Showing the first eight; more decompositions exist.
