Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045260, here are decompositions:

19 + 1045241 = 1045260
23 + 1045237 = 1045260
31 + 1045229 = 1045260
37 + 1045223 = 1045260
61 + 1045199 = 1045260
67 + 1045193 = 1045260
103 + 1045157 = 1045260
107 + 1045153 = 1045260

Showing the first eight; more decompositions exist.
