Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681360, here are decompositions:

3 + 8681357 = 8681360
19 + 8681341 = 8681360
43 + 8681317 = 8681360
73 + 8681287 = 8681360
97 + 8681263 = 8681360
109 + 8681251 = 8681360
139 + 8681221 = 8681360
229 + 8681131 = 8681360

Showing the first eight; more decompositions exist.
