Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671260, here are decompositions:

11 + 8671249 = 8671260
29 + 8671231 = 8671260
41 + 8671219 = 8671260
67 + 8671193 = 8671260
83 + 8671177 = 8671260
109 + 8671151 = 8671260
113 + 8671147 = 8671260
127 + 8671133 = 8671260

Showing the first eight; more decompositions exist.
