Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468338, here are decompositions:

7 + 31468331 = 31468338
19 + 31468319 = 31468338
67 + 31468271 = 31468338
79 + 31468259 = 31468338
107 + 31468231 = 31468338
127 + 31468211 = 31468338
137 + 31468201 = 31468338
179 + 31468159 = 31468338

Showing the first eight; more decompositions exist.
