Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42286, here are decompositions:

3 + 42283 = 42286
5 + 42281 = 42286
29 + 42257 = 42286
47 + 42239 = 42286
59 + 42227 = 42286
89 + 42197 = 42286
107 + 42179 = 42286
197 + 42089 = 42286

Showing the first eight; more decompositions exist.
