Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009242, here are decompositions:

5 + 1009237 = 1009242
41 + 1009201 = 1009242
43 + 1009199 = 1009242
53 + 1009189 = 1009242
79 + 1009163 = 1009242
83 + 1009159 = 1009242
89 + 1009153 = 1009242
103 + 1009139 = 1009242

Showing the first eight; more decompositions exist.
