Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028144, here are decompositions:

3 + 1028141 = 1028144
31 + 1028113 = 1028144
37 + 1028107 = 1028144
43 + 1028101 = 1028144
97 + 1028047 = 1028144
127 + 1028017 = 1028144
157 + 1027987 = 1028144
367 + 1027777 = 1028144

Showing the first eight; more decompositions exist.
