Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554844, here are decompositions:

3 + 31554841 = 31554844
47 + 31554797 = 31554844
53 + 31554791 = 31554844
173 + 31554671 = 31554844
227 + 31554617 = 31554844
317 + 31554527 = 31554844
443 + 31554401 = 31554844
557 + 31554287 = 31554844

Showing the first eight; more decompositions exist.
