Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453444, here are decompositions:

17 + 31453427 = 31453444
23 + 31453421 = 31453444
53 + 31453391 = 31453444
83 + 31453361 = 31453444
251 + 31453193 = 31453444
263 + 31453181 = 31453444
311 + 31453133 = 31453444
467 + 31452977 = 31453444

Showing the first eight; more decompositions exist.
