Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732180, here are decompositions:

43 + 8732137 = 8732180
109 + 8732071 = 8732180
151 + 8732029 = 8732180
157 + 8732023 = 8732180
199 + 8731981 = 8732180
229 + 8731951 = 8732180
241 + 8731939 = 8732180
307 + 8731873 = 8732180

Showing the first eight; more decompositions exist.
