Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493350, here are decompositions:

3 + 31493347 = 31493350
11 + 31493339 = 31493350
29 + 31493321 = 31493350
59 + 31493291 = 31493350
101 + 31493249 = 31493350
149 + 31493201 = 31493350
179 + 31493171 = 31493350
197 + 31493153 = 31493350

Showing the first eight; more decompositions exist.
