Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736180, here are decompositions:

7 + 8736173 = 8736180
41 + 8736139 = 8736180
53 + 8736127 = 8736180
71 + 8736109 = 8736180
83 + 8736097 = 8736180
107 + 8736073 = 8736180
139 + 8736041 = 8736180
179 + 8736001 = 8736180

Showing the first eight; more decompositions exist.
