Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021144, here are decompositions:

17 + 1021127 = 1021144
53 + 1021091 = 1021144
71 + 1021073 = 1021144
101 + 1021043 = 1021144
167 + 1020977 = 1021144
251 + 1020893 = 1021144
263 + 1020881 = 1021144
317 + 1020827 = 1021144

Showing the first eight; more decompositions exist.
