Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468452, here are decompositions:

5 + 31468447 = 31468452
53 + 31468399 = 31468452
61 + 31468391 = 31468452
83 + 31468369 = 31468452
163 + 31468289 = 31468452
181 + 31468271 = 31468452
193 + 31468259 = 31468452
229 + 31468223 = 31468452

Showing the first eight; more decompositions exist.
