Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1011242, here are decompositions:

3 + 1011239 = 1011242
13 + 1011229 = 1011242
79 + 1011163 = 1011242
103 + 1011139 = 1011242
151 + 1011091 = 1011242
163 + 1011079 = 1011242
229 + 1011013 = 1011242
241 + 1011001 = 1011242

Showing the first eight; more decompositions exist.
