Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020928, here are decompositions:

47 + 1020881 = 1020928
89 + 1020839 = 1020928
101 + 1020827 = 1020928
107 + 1020821 = 1020928
131 + 1020797 = 1020928
149 + 1020779 = 1020928
239 + 1020689 = 1020928
509 + 1020419 = 1020928

Showing the first eight; more decompositions exist.
