Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468344, here are decompositions:

7 + 31468337 = 31468344
13 + 31468331 = 31468344
73 + 31468271 = 31468344
97 + 31468247 = 31468344
101 + 31468243 = 31468344
113 + 31468231 = 31468344
197 + 31468147 = 31468344
277 + 31468067 = 31468344

Showing the first eight; more decompositions exist.
