Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42290, here are decompositions:

7 + 42283 = 42290
67 + 42223 = 42290
97 + 42193 = 42290
103 + 42187 = 42290
109 + 42181 = 42290
151 + 42139 = 42290
229 + 42061 = 42290
271 + 42019 = 42290

Showing the first eight; more decompositions exist.
