Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448432, here are decompositions:

19 + 31448413 = 31448432
109 + 31448323 = 31448432
139 + 31448293 = 31448432
151 + 31448281 = 31448432
199 + 31448233 = 31448432
241 + 31448191 = 31448432
271 + 31448161 = 31448432
283 + 31448149 = 31448432

Showing the first eight; more decompositions exist.
