Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449822, here are decompositions:

31 + 31449791 = 31449822
71 + 31449751 = 31449822
83 + 31449739 = 31449822
149 + 31449673 = 31449822
193 + 31449629 = 31449822
211 + 31449611 = 31449822
233 + 31449589 = 31449822
241 + 31449581 = 31449822

Showing the first eight; more decompositions exist.
