Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728830, here are decompositions:

7 + 8728823 = 8728830
23 + 8728807 = 8728830
43 + 8728787 = 8728830
73 + 8728757 = 8728830
109 + 8728721 = 8728830
113 + 8728717 = 8728830
139 + 8728691 = 8728830
151 + 8728679 = 8728830

Showing the first eight; more decompositions exist.
