Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756218, here are decompositions:

5 + 8756213 = 8756218
17 + 8756201 = 8756218
59 + 8756159 = 8756218
89 + 8756129 = 8756218
101 + 8756117 = 8756218
167 + 8756051 = 8756218
179 + 8756039 = 8756218
197 + 8756021 = 8756218

Showing the first eight; more decompositions exist.
