Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449484, here are decompositions:

5 + 31449479 = 31449484
83 + 31449401 = 31449484
107 + 31449377 = 31449484
197 + 31449287 = 31449484
251 + 31449233 = 31449484
293 + 31449191 = 31449484
401 + 31449083 = 31449484
431 + 31449053 = 31449484

Showing the first eight; more decompositions exist.
