Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449592, here are decompositions:

3 + 31449589 = 31449592
11 + 31449581 = 31449592
23 + 31449569 = 31449592
113 + 31449479 = 31449592
191 + 31449401 = 31449592
233 + 31449359 = 31449592
269 + 31449323 = 31449592
359 + 31449233 = 31449592

Showing the first eight; more decompositions exist.
