Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021102, here are decompositions:

11 + 1021091 = 1021102
29 + 1021073 = 1021102
59 + 1021043 = 1021102
83 + 1021019 = 1021102
101 + 1021001 = 1021102
113 + 1020989 = 1021102
263 + 1020839 = 1021102
281 + 1020821 = 1021102

Showing the first eight; more decompositions exist.
