Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468342, here are decompositions:

5 + 31468337 = 31468342
11 + 31468331 = 31468342
23 + 31468319 = 31468342
53 + 31468289 = 31468342
71 + 31468271 = 31468342
83 + 31468259 = 31468342
131 + 31468211 = 31468342
173 + 31468169 = 31468342

Showing the first eight; more decompositions exist.
