Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468396, here are decompositions:

5 + 31468391 = 31468396
59 + 31468337 = 31468396
107 + 31468289 = 31468396
137 + 31468259 = 31468396
149 + 31468247 = 31468396
173 + 31468223 = 31468396
227 + 31468169 = 31468396
383 + 31468013 = 31468396

Showing the first eight; more decompositions exist.
