Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468444, here are decompositions:

41 + 31468403 = 31468444
47 + 31468397 = 31468444
53 + 31468391 = 31468444
107 + 31468337 = 31468444
113 + 31468331 = 31468444
173 + 31468271 = 31468444
197 + 31468247 = 31468444
233 + 31468211 = 31468444

Showing the first eight; more decompositions exist.
