Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020102, here are decompositions:

23 + 1020079 = 1020102
43 + 1020059 = 1020102
53 + 1020049 = 1020102
59 + 1020043 = 1020102
79 + 1020023 = 1020102
89 + 1020013 = 1020102
101 + 1020001 = 1020102
131 + 1019971 = 1020102

Showing the first eight; more decompositions exist.
