Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730666, here are decompositions:

5 + 8730661 = 8730666
17 + 8730649 = 8730666
37 + 8730629 = 8730666
47 + 8730619 = 8730666
59 + 8730607 = 8730666
83 + 8730583 = 8730666
89 + 8730577 = 8730666
107 + 8730559 = 8730666

Showing the first eight; more decompositions exist.
