Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448342, here are decompositions:

19 + 31448323 = 31448342
43 + 31448299 = 31448342
61 + 31448281 = 31448342
109 + 31448233 = 31448342
151 + 31448191 = 31448342
181 + 31448161 = 31448342
193 + 31448149 = 31448342
271 + 31448071 = 31448342

Showing the first eight; more decompositions exist.
