Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453452, here are decompositions:

5 + 31453447 = 31453452
31 + 31453421 = 31453452
59 + 31453393 = 31453452
61 + 31453391 = 31453452
131 + 31453321 = 31453452
211 + 31453241 = 31453452
271 + 31453181 = 31453452
281 + 31453171 = 31453452

Showing the first eight; more decompositions exist.
