Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468332, here are decompositions:

13 + 31468319 = 31468332
43 + 31468289 = 31468332
61 + 31468271 = 31468332
73 + 31468259 = 31468332
89 + 31468243 = 31468332
101 + 31468231 = 31468332
109 + 31468223 = 31468332
131 + 31468201 = 31468332

Showing the first eight; more decompositions exist.
