Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84242, here are decompositions:

3 + 84239 = 84242
13 + 84229 = 84242
19 + 84223 = 84242
31 + 84211 = 84242
43 + 84199 = 84242
61 + 84181 = 84242
79 + 84163 = 84242
181 + 84061 = 84242

Showing the first eight; more decompositions exist.
