Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8704218, here are decompositions:

59 + 8704159 = 8704218
97 + 8704121 = 8704218
101 + 8704117 = 8704218
151 + 8704067 = 8704218
191 + 8704027 = 8704218
307 + 8703911 = 8704218
359 + 8703859 = 8704218
389 + 8703829 = 8704218

Showing the first eight; more decompositions exist.
