Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749830, here are decompositions:

13 + 8749817 = 8749830
17 + 8749813 = 8749830
41 + 8749789 = 8749830
43 + 8749787 = 8749830
59 + 8749771 = 8749830
79 + 8749751 = 8749830
97 + 8749733 = 8749830
179 + 8749651 = 8749830

Showing the first eight; more decompositions exist.
