Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468414, here are decompositions:

11 + 31468403 = 31468414
17 + 31468397 = 31468414
23 + 31468391 = 31468414
83 + 31468331 = 31468414
167 + 31468247 = 31468414
191 + 31468223 = 31468414
317 + 31468097 = 31468414
347 + 31468067 = 31468414

Showing the first eight; more decompositions exist.
