Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697228, here are decompositions:

101 + 8697127 = 8697228
131 + 8697097 = 8697228
139 + 8697089 = 8697228
167 + 8697061 = 8697228
179 + 8697049 = 8697228
191 + 8697037 = 8697228
229 + 8696999 = 8697228
251 + 8696977 = 8697228

Showing the first eight; more decompositions exist.
