Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468258, here are decompositions:

11 + 31468247 = 31468258
47 + 31468211 = 31468258
89 + 31468169 = 31468258
191 + 31468067 = 31468258
257 + 31468001 = 31468258
347 + 31467911 = 31468258
359 + 31467899 = 31468258
449 + 31467809 = 31468258

Showing the first eight; more decompositions exist.
