Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101228, here are decompositions:

7 + 101221 = 101228
19 + 101209 = 101228
31 + 101197 = 101228
67 + 101161 = 101228
79 + 101149 = 101228
109 + 101119 = 101228
139 + 101089 = 101228
229 + 100999 = 101228

Showing the first eight; more decompositions exist.
