Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736380, here are decompositions:

13 + 8736367 = 8736380
157 + 8736223 = 8736380
181 + 8736199 = 8736380
193 + 8736187 = 8736380
241 + 8736139 = 8736380
271 + 8736109 = 8736380
283 + 8736097 = 8736380
307 + 8736073 = 8736380

Showing the first eight; more decompositions exist.
