Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468380, here are decompositions:

11 + 31468369 = 31468380
43 + 31468337 = 31468380
61 + 31468319 = 31468380
109 + 31468271 = 31468380
137 + 31468243 = 31468380
149 + 31468231 = 31468380
157 + 31468223 = 31468380
179 + 31468201 = 31468380

Showing the first eight; more decompositions exist.
