Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101210, here are decompositions:

3 + 101207 = 101210
7 + 101203 = 101210
13 + 101197 = 101210
37 + 101173 = 101210
61 + 101149 = 101210
97 + 101113 = 101210
103 + 101107 = 101210
211 + 100999 = 101210

Showing the first eight; more decompositions exist.
