Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456366, here are decompositions:

5 + 31456361 = 31456366
47 + 31456319 = 31456366
89 + 31456277 = 31456366
107 + 31456259 = 31456366
167 + 31456199 = 31456366
173 + 31456193 = 31456366
353 + 31456013 = 31456366
419 + 31455947 = 31456366

Showing the first eight; more decompositions exist.
