Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468528, here are decompositions:

5 + 31468523 = 31468528
11 + 31468517 = 31468528
17 + 31468511 = 31468528
29 + 31468499 = 31468528
131 + 31468397 = 31468528
137 + 31468391 = 31468528
191 + 31468337 = 31468528
197 + 31468331 = 31468528

Showing the first eight; more decompositions exist.
