Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101220, here are decompositions:

11 + 101209 = 101220
13 + 101207 = 101220
17 + 101203 = 101220
23 + 101197 = 101220
37 + 101183 = 101220
47 + 101173 = 101220
59 + 101161 = 101220
61 + 101159 = 101220

Showing the first eight; more decompositions exist.
