Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494444, here are decompositions:

5 + 31494439 = 31494444
13 + 31494431 = 31494444
17 + 31494427 = 31494444
43 + 31494401 = 31494444
97 + 31494347 = 31494444
151 + 31494293 = 31494444
181 + 31494263 = 31494444
197 + 31494247 = 31494444

Showing the first eight; more decompositions exist.
