Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005242, here are decompositions:

3 + 1005239 = 1005242
13 + 1005229 = 1005242
19 + 1005223 = 1005242
109 + 1005133 = 1005242
163 + 1005079 = 1005242
193 + 1005049 = 1005242
223 + 1005019 = 1005242
229 + 1005013 = 1005242

Showing the first eight; more decompositions exist.
