Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102888, here are decompositions:

7 + 102881 = 102888
11 + 102877 = 102888
17 + 102871 = 102888
29 + 102859 = 102888
47 + 102841 = 102888
59 + 102829 = 102888
127 + 102761 = 102888
211 + 102677 = 102888

Showing the first eight; more decompositions exist.
