Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448326, here are decompositions:

3 + 31448323 = 31448326
5 + 31448321 = 31448326
17 + 31448309 = 31448326
23 + 31448303 = 31448326
29 + 31448297 = 31448326
257 + 31448069 = 31448326
269 + 31448057 = 31448326
293 + 31448033 = 31448326

Showing the first eight; more decompositions exist.
