Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701218, here are decompositions:

7 + 8701211 = 8701218
11 + 8701207 = 8701218
41 + 8701177 = 8701218
101 + 8701117 = 8701218
137 + 8701081 = 8701218
151 + 8701067 = 8701218
179 + 8701039 = 8701218
191 + 8701027 = 8701218

Showing the first eight; more decompositions exist.
