Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576444, here are decompositions:

5 + 31576439 = 31576444
17 + 31576427 = 31576444
41 + 31576403 = 31576444
71 + 31576373 = 31576444
191 + 31576253 = 31576444
233 + 31576211 = 31576444
257 + 31576187 = 31576444
281 + 31576163 = 31576444

Showing the first eight; more decompositions exist.
