Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661332, here are decompositions:

79 + 8661253 = 8661332
109 + 8661223 = 8661332
139 + 8661193 = 8661332
151 + 8661181 = 8661332
271 + 8661061 = 8661332
283 + 8661049 = 8661332
331 + 8661001 = 8661332
349 + 8660983 = 8661332

Showing the first eight; more decompositions exist.
