Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468312, here are decompositions:

23 + 31468289 = 31468312
41 + 31468271 = 31468312
53 + 31468259 = 31468312
89 + 31468223 = 31468312
101 + 31468211 = 31468312
311 + 31468001 = 31468312
401 + 31467911 = 31468312
419 + 31467893 = 31468312

Showing the first eight; more decompositions exist.
