Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448382, here are decompositions:

5 + 31448377 = 31448382
13 + 31448369 = 31448382
59 + 31448323 = 31448382
61 + 31448321 = 31448382
73 + 31448309 = 31448382
79 + 31448303 = 31448382
83 + 31448299 = 31448382
89 + 31448293 = 31448382

Showing the first eight; more decompositions exist.
