Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456350, here are decompositions:

19 + 31456331 = 31456350
31 + 31456319 = 31456350
59 + 31456291 = 31456350
71 + 31456279 = 31456350
73 + 31456277 = 31456350
103 + 31456247 = 31456350
109 + 31456241 = 31456350
113 + 31456237 = 31456350

Showing the first eight; more decompositions exist.
