Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617248, here are decompositions:

11 + 8617237 = 8617248
37 + 8617211 = 8617248
41 + 8617207 = 8617248
47 + 8617201 = 8617248
61 + 8617187 = 8617248
71 + 8617177 = 8617248
139 + 8617109 = 8617248
151 + 8617097 = 8617248

Showing the first eight; more decompositions exist.
