Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617880, here are decompositions:

3 + 8617877 = 8617880
43 + 8617837 = 8617880
127 + 8617753 = 8617880
181 + 8617699 = 8617880
199 + 8617681 = 8617880
331 + 8617549 = 8617880
367 + 8617513 = 8617880
433 + 8617447 = 8617880

Showing the first eight; more decompositions exist.
