Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482444, here are decompositions:

5 + 31482439 = 31482444
17 + 31482427 = 31482444
43 + 31482401 = 31482444
101 + 31482343 = 31482444
107 + 31482337 = 31482444
137 + 31482307 = 31482444
151 + 31482293 = 31482444
163 + 31482281 = 31482444

Showing the first eight; more decompositions exist.
