Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661300, here are decompositions:

19 + 8661281 = 8661300
47 + 8661253 = 8661300
59 + 8661241 = 8661300
61 + 8661239 = 8661300
83 + 8661217 = 8661300
97 + 8661203 = 8661300
103 + 8661197 = 8661300
107 + 8661193 = 8661300

Showing the first eight; more decompositions exist.
