Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468450, here are decompositions:

3 + 31468447 = 31468450
47 + 31468403 = 31468450
53 + 31468397 = 31468450
59 + 31468391 = 31468450
113 + 31468337 = 31468450
131 + 31468319 = 31468450
179 + 31468271 = 31468450
191 + 31468259 = 31468450

Showing the first eight; more decompositions exist.
