Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468458, here are decompositions:

5 + 31468453 = 31468458
11 + 31468447 = 31468458
59 + 31468399 = 31468458
61 + 31468397 = 31468458
67 + 31468391 = 31468458
89 + 31468369 = 31468458
127 + 31468331 = 31468458
139 + 31468319 = 31468458

Showing the first eight; more decompositions exist.
