Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700166, here are decompositions:

5 + 8700161 = 8700166
53 + 8700113 = 8700166
107 + 8700059 = 8700166
173 + 8699993 = 8700166
197 + 8699969 = 8700166
353 + 8699813 = 8700166
359 + 8699807 = 8700166
443 + 8699723 = 8700166

Showing the first eight; more decompositions exist.
