Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661326, here are decompositions:

73 + 8661253 = 8661326
103 + 8661223 = 8661326
109 + 8661217 = 8661326
277 + 8661049 = 8661326
283 + 8661043 = 8661326
379 + 8660947 = 8661326
397 + 8660929 = 8661326
439 + 8660887 = 8661326

Showing the first eight; more decompositions exist.
