Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448336, here are decompositions:

13 + 31448323 = 31448336
37 + 31448299 = 31448336
43 + 31448293 = 31448336
103 + 31448233 = 31448336
313 + 31448023 = 31448336
349 + 31447987 = 31448336
373 + 31447963 = 31448336
379 + 31447957 = 31448336

Showing the first eight; more decompositions exist.
