Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021180, here are decompositions:

23 + 1021157 = 1021180
53 + 1021127 = 1021180
89 + 1021091 = 1021180
107 + 1021073 = 1021180
113 + 1021067 = 1021180
137 + 1021043 = 1021180
179 + 1021001 = 1021180
191 + 1020989 = 1021180

Showing the first eight; more decompositions exist.
