Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448352, here are decompositions:

29 + 31448323 = 31448352
31 + 31448321 = 31448352
43 + 31448309 = 31448352
53 + 31448299 = 31448352
59 + 31448293 = 31448352
71 + 31448281 = 31448352
151 + 31448201 = 31448352
181 + 31448171 = 31448352

Showing the first eight; more decompositions exist.
