Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449882, here are decompositions:

11 + 31449871 = 31449882
29 + 31449853 = 31449882
59 + 31449823 = 31449882
131 + 31449751 = 31449882
181 + 31449701 = 31449882
193 + 31449689 = 31449882
263 + 31449619 = 31449882
271 + 31449611 = 31449882

Showing the first eight; more decompositions exist.
