Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90242, here are decompositions:

3 + 90239 = 90242
43 + 90199 = 90242
79 + 90163 = 90242
211 + 90031 = 90242
223 + 90019 = 90242
241 + 90001 = 90242
283 + 89959 = 90242
409 + 89833 = 90242

Showing the first eight; more decompositions exist.
