Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702180, here are decompositions:

7 + 8702173 = 8702180
31 + 8702149 = 8702180
43 + 8702137 = 8702180
73 + 8702107 = 8702180
181 + 8701999 = 8702180
229 + 8701951 = 8702180
307 + 8701873 = 8702180
367 + 8701813 = 8702180

Showing the first eight; more decompositions exist.
