Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667180, here are decompositions:

13 + 8667167 = 8667180
29 + 8667151 = 8667180
43 + 8667137 = 8667180
59 + 8667121 = 8667180
101 + 8667079 = 8667180
191 + 8666989 = 8667180
227 + 8666953 = 8667180
241 + 8666939 = 8667180

Showing the first eight; more decompositions exist.
