Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449622, here are decompositions:

3 + 31449619 = 31449622
11 + 31449611 = 31449622
41 + 31449581 = 31449622
53 + 31449569 = 31449622
173 + 31449449 = 31449622
263 + 31449359 = 31449622
359 + 31449263 = 31449622
389 + 31449233 = 31449622

Showing the first eight; more decompositions exist.
