Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84290, here are decompositions:

43 + 84247 = 84290
61 + 84229 = 84290
67 + 84223 = 84290
79 + 84211 = 84290
109 + 84181 = 84290
127 + 84163 = 84290
163 + 84127 = 84290
223 + 84067 = 84290

Showing the first eight; more decompositions exist.
