Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449574, here are decompositions:

3 + 31449571 = 31449574
5 + 31449569 = 31449574
17 + 31449557 = 31449574
47 + 31449527 = 31449574
173 + 31449401 = 31449574
197 + 31449377 = 31449574
251 + 31449323 = 31449574
311 + 31449263 = 31449574

Showing the first eight; more decompositions exist.
