Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471444, here are decompositions:

5 + 31471439 = 31471444
47 + 31471397 = 31471444
71 + 31471373 = 31471444
83 + 31471361 = 31471444
113 + 31471331 = 31471444
227 + 31471217 = 31471444
353 + 31471091 = 31471444
401 + 31471043 = 31471444

Showing the first eight; more decompositions exist.
