Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468392, here are decompositions:

23 + 31468369 = 31468392
61 + 31468331 = 31468392
73 + 31468319 = 31468392
103 + 31468289 = 31468392
149 + 31468243 = 31468392
181 + 31468211 = 31468392
191 + 31468201 = 31468392
223 + 31468169 = 31468392

Showing the first eight; more decompositions exist.
