Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448310, here are decompositions:

7 + 31448303 = 31448310
11 + 31448299 = 31448310
13 + 31448297 = 31448310
17 + 31448293 = 31448310
29 + 31448281 = 31448310
109 + 31448201 = 31448310
139 + 31448171 = 31448310
149 + 31448161 = 31448310

Showing the first eight; more decompositions exist.
