Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101288, here are decompositions:

7 + 101281 = 101288
67 + 101221 = 101288
79 + 101209 = 101288
127 + 101161 = 101288
139 + 101149 = 101288
181 + 101107 = 101288
199 + 101089 = 101288
307 + 100981 = 101288

Showing the first eight; more decompositions exist.
