Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493332, here are decompositions:

11 + 31493321 = 31493332
41 + 31493291 = 31493332
83 + 31493249 = 31493332
131 + 31493201 = 31493332
179 + 31493153 = 31493332
263 + 31493069 = 31493332
293 + 31493039 = 31493332
389 + 31492943 = 31493332

Showing the first eight; more decompositions exist.
