Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493326, here are decompositions:

3 + 31493323 = 31493326
5 + 31493321 = 31493326
173 + 31493153 = 31493326
257 + 31493069 = 31493326
269 + 31493057 = 31493326
317 + 31493009 = 31493326
383 + 31492943 = 31493326
419 + 31492907 = 31493326

Showing the first eight; more decompositions exist.
