Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42454, here are decompositions:

3 + 42451 = 42454
11 + 42443 = 42454
17 + 42437 = 42454
47 + 42407 = 42454
131 + 42323 = 42454
173 + 42281 = 42454
197 + 42257 = 42454
227 + 42227 = 42454

Showing the first eight; more decompositions exist.
