Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449582, here are decompositions:

5 + 31449577 = 31449582
11 + 31449571 = 31449582
13 + 31449569 = 31449582
29 + 31449553 = 31449582
83 + 31449499 = 31449582
89 + 31449493 = 31449582
103 + 31449479 = 31449582
173 + 31449409 = 31449582

Showing the first eight; more decompositions exist.
