Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449648, here are decompositions:

11 + 31449637 = 31449648
19 + 31449629 = 31449648
29 + 31449619 = 31449648
37 + 31449611 = 31449648
59 + 31449589 = 31449648
67 + 31449581 = 31449648
71 + 31449577 = 31449648
79 + 31449569 = 31449648

Showing the first eight; more decompositions exist.
