Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497354, here are decompositions:

13 + 31497341 = 31497354
17 + 31497337 = 31497354
41 + 31497313 = 31497354
61 + 31497293 = 31497354
67 + 31497287 = 31497354
71 + 31497283 = 31497354
103 + 31497251 = 31497354
131 + 31497223 = 31497354

Showing the first eight; more decompositions exist.
