Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468548, here are decompositions:

5 + 31468543 = 31468548
19 + 31468529 = 31468548
31 + 31468517 = 31468548
37 + 31468511 = 31468548
101 + 31468447 = 31468548
149 + 31468399 = 31468548
151 + 31468397 = 31468548
157 + 31468391 = 31468548

Showing the first eight; more decompositions exist.
