Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617280, here are decompositions:

3 + 8617277 = 8617280
19 + 8617261 = 8617280
43 + 8617237 = 8617280
73 + 8617207 = 8617280
79 + 8617201 = 8617280
103 + 8617177 = 8617280
109 + 8617171 = 8617280
127 + 8617153 = 8617280

Showing the first eight; more decompositions exist.
