Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554752, here are decompositions:

3 + 31554749 = 31554752
13 + 31554739 = 31554752
43 + 31554709 = 31554752
139 + 31554613 = 31554752
181 + 31554571 = 31554752
211 + 31554541 = 31554752
241 + 31554511 = 31554752
571 + 31554181 = 31554752

Showing the first eight; more decompositions exist.
