Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 88100, here are decompositions:

7 + 88093 = 88100
31 + 88069 = 88100
97 + 88003 = 88100
109 + 87991 = 88100
127 + 87973 = 88100
139 + 87961 = 88100
157 + 87943 = 88100
223 + 87877 = 88100

Showing the first eight; more decompositions exist.
