Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018284, here are decompositions:

13 + 1018271 = 1018284
31 + 1018253 = 1018284
37 + 1018247 = 1018284
61 + 1018223 = 1018284
67 + 1018217 = 1018284
83 + 1018201 = 1018284
107 + 1018177 = 1018284
193 + 1018091 = 1018284

Showing the first eight; more decompositions exist.
