Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448582, here are decompositions:

3 + 31448579 = 31448582
31 + 31448551 = 31448582
103 + 31448479 = 31448582
283 + 31448299 = 31448582
349 + 31448233 = 31448582
421 + 31448161 = 31448582
433 + 31448149 = 31448582
619 + 31447963 = 31448582

Showing the first eight; more decompositions exist.
