Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736880, here are decompositions:

71 + 8736809 = 8736880
179 + 8736701 = 8736880
197 + 8736683 = 8736880
227 + 8736653 = 8736880
233 + 8736647 = 8736880
263 + 8736617 = 8736880
419 + 8736461 = 8736880
431 + 8736449 = 8736880

Showing the first eight; more decompositions exist.
