Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449056, here are decompositions:

3 + 31449053 = 31449056
13 + 31449043 = 31449056
19 + 31449037 = 31449056
157 + 31448899 = 31449056
193 + 31448863 = 31449056
337 + 31448719 = 31449056
349 + 31448707 = 31449056
409 + 31448647 = 31449056

Showing the first eight; more decompositions exist.
