Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8704180, here are decompositions:

11 + 8704169 = 8704180
59 + 8704121 = 8704180
113 + 8704067 = 8704180
131 + 8704049 = 8704180
269 + 8703911 = 8704180
281 + 8703899 = 8704180
347 + 8703833 = 8704180
461 + 8703719 = 8704180

Showing the first eight; more decompositions exist.
