Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990242, here are decompositions:

3 + 990239 = 990242
31 + 990211 = 990242
61 + 990181 = 990242
73 + 990169 = 990242
79 + 990163 = 990242
199 + 990043 = 990242
229 + 990013 = 990242
241 + 990001 = 990242

Showing the first eight; more decompositions exist.
