Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740180, here are decompositions:

11 + 8740169 = 8740180
17 + 8740163 = 8740180
23 + 8740157 = 8740180
41 + 8740139 = 8740180
83 + 8740097 = 8740180
227 + 8739953 = 8740180
263 + 8739917 = 8740180
269 + 8739911 = 8740180

Showing the first eight; more decompositions exist.
