Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493358, here are decompositions:

5 + 31493353 = 31493358
11 + 31493347 = 31493358
19 + 31493339 = 31493358
37 + 31493321 = 31493358
67 + 31493291 = 31493358
107 + 31493251 = 31493358
109 + 31493249 = 31493358
157 + 31493201 = 31493358

Showing the first eight; more decompositions exist.
