Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021230, here are decompositions:

13 + 1021217 = 1021230
31 + 1021199 = 1021230
47 + 1021183 = 1021230
71 + 1021159 = 1021230
73 + 1021157 = 1021230
101 + 1021129 = 1021230
103 + 1021127 = 1021230
107 + 1021123 = 1021230

Showing the first eight; more decompositions exist.
