Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449682, here are decompositions:

3 + 31449679 = 31449682
53 + 31449629 = 31449682
71 + 31449611 = 31449682
101 + 31449581 = 31449682
113 + 31449569 = 31449682
233 + 31449449 = 31449682
281 + 31449401 = 31449682
359 + 31449323 = 31449682

Showing the first eight; more decompositions exist.
