Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690180, here are decompositions:

3 + 8690177 = 8690180
7 + 8690173 = 8690180
61 + 8690119 = 8690180
139 + 8690041 = 8690180
193 + 8689987 = 8690180
199 + 8689981 = 8690180
211 + 8689969 = 8690180
223 + 8689957 = 8690180

Showing the first eight; more decompositions exist.
