Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1011286, here are decompositions:

5 + 1011281 = 1011286
47 + 1011239 = 1011286
53 + 1011233 = 1011286
149 + 1011137 = 1011286
179 + 1011107 = 1011286
257 + 1011029 = 1011286
293 + 1010993 = 1011286
383 + 1010903 = 1011286

Showing the first eight; more decompositions exist.
