Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493362, here are decompositions:

23 + 31493339 = 31493362
41 + 31493321 = 31493362
71 + 31493291 = 31493362
113 + 31493249 = 31493362
191 + 31493171 = 31493362
293 + 31493069 = 31493362
353 + 31493009 = 31493362
419 + 31492943 = 31493362

Showing the first eight; more decompositions exist.
