Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452346, here are decompositions:

5 + 31452341 = 31452346
113 + 31452233 = 31452346
137 + 31452209 = 31452346
173 + 31452173 = 31452346
257 + 31452089 = 31452346
347 + 31451999 = 31452346
353 + 31451993 = 31452346
509 + 31451837 = 31452346

Showing the first eight; more decompositions exist.
