Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449632, here are decompositions:

3 + 31449629 = 31449632
13 + 31449619 = 31449632
43 + 31449589 = 31449632
61 + 31449571 = 31449632
79 + 31449553 = 31449632
139 + 31449493 = 31449632
211 + 31449421 = 31449632
223 + 31449409 = 31449632

Showing the first eight; more decompositions exist.
