Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101216, here are decompositions:

7 + 101209 = 101216
13 + 101203 = 101216
19 + 101197 = 101216
43 + 101173 = 101216
67 + 101149 = 101216
97 + 101119 = 101216
103 + 101113 = 101216
109 + 101107 = 101216

Showing the first eight; more decompositions exist.
