Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468350, here are decompositions:

13 + 31468337 = 31468350
19 + 31468331 = 31468350
31 + 31468319 = 31468350
61 + 31468289 = 31468350
79 + 31468271 = 31468350
103 + 31468247 = 31468350
107 + 31468243 = 31468350
127 + 31468223 = 31468350

Showing the first eight; more decompositions exist.
