Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468368, here are decompositions:

31 + 31468337 = 31468368
37 + 31468331 = 31468368
79 + 31468289 = 31468368
97 + 31468271 = 31468368
109 + 31468259 = 31468368
137 + 31468231 = 31468368
157 + 31468211 = 31468368
167 + 31468201 = 31468368

Showing the first eight; more decompositions exist.
