Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636180, here are decompositions:

13 + 8636167 = 8636180
43 + 8636137 = 8636180
73 + 8636107 = 8636180
97 + 8636083 = 8636180
181 + 8635999 = 8636180
199 + 8635981 = 8636180
211 + 8635969 = 8636180
229 + 8635951 = 8636180

Showing the first eight; more decompositions exist.
