Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456332, here are decompositions:

13 + 31456319 = 31456332
41 + 31456291 = 31456332
53 + 31456279 = 31456332
73 + 31456259 = 31456332
113 + 31456219 = 31456332
139 + 31456193 = 31456332
211 + 31456121 = 31456332
233 + 31456099 = 31456332

Showing the first eight; more decompositions exist.
