Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464444, here are decompositions:

5 + 31464439 = 31464444
17 + 31464427 = 31464444
23 + 31464421 = 31464444
43 + 31464401 = 31464444
47 + 31464397 = 31464444
103 + 31464341 = 31464444
163 + 31464281 = 31464444
173 + 31464271 = 31464444

Showing the first eight; more decompositions exist.
