Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617100, here are decompositions:

3 + 8617097 = 8617100
103 + 8616997 = 8617100
109 + 8616991 = 8617100
181 + 8616919 = 8617100
199 + 8616901 = 8617100
241 + 8616859 = 8617100
337 + 8616763 = 8617100
367 + 8616733 = 8617100

Showing the first eight; more decompositions exist.
