Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8755180, here are decompositions:

3 + 8755177 = 8755180
59 + 8755121 = 8755180
101 + 8755079 = 8755180
107 + 8755073 = 8755180
131 + 8755049 = 8755180
149 + 8755031 = 8755180
179 + 8755001 = 8755180
263 + 8754917 = 8755180

Showing the first eight; more decompositions exist.
