Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448426, here are decompositions:

3 + 31448423 = 31448426
13 + 31448413 = 31448426
103 + 31448323 = 31448426
127 + 31448299 = 31448426
193 + 31448233 = 31448426
277 + 31448149 = 31448426
409 + 31448017 = 31448426
439 + 31447987 = 31448426

Showing the first eight; more decompositions exist.
