Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101028, here are decompositions:

7 + 101021 = 101028
19 + 101009 = 101028
29 + 100999 = 101028
41 + 100987 = 101028
47 + 100981 = 101028
71 + 100957 = 101028
97 + 100931 = 101028
101 + 100927 = 101028

Showing the first eight; more decompositions exist.
