Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468384, here are decompositions:

47 + 31468337 = 31468384
53 + 31468331 = 31468384
113 + 31468271 = 31468384
137 + 31468247 = 31468384
173 + 31468211 = 31468384
317 + 31468067 = 31468384
383 + 31468001 = 31468384
401 + 31467983 = 31468384

Showing the first eight; more decompositions exist.
