Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454358, here are decompositions:

7 + 31454351 = 31454358
37 + 31454321 = 31454358
109 + 31454249 = 31454358
137 + 31454221 = 31454358
139 + 31454219 = 31454358
157 + 31454201 = 31454358
167 + 31454191 = 31454358
197 + 31454161 = 31454358

Showing the first eight; more decompositions exist.
