Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493354, here are decompositions:

7 + 31493347 = 31493354
31 + 31493323 = 31493354
103 + 31493251 = 31493354
163 + 31493191 = 31493354
223 + 31493131 = 31493354
271 + 31493083 = 31493354
307 + 31493047 = 31493354
337 + 31493017 = 31493354

Showing the first eight; more decompositions exist.
