Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728232, here are decompositions:

103 + 8728129 = 8728232
613 + 8727619 = 8728232
631 + 8727601 = 8728232
739 + 8727493 = 8728232
883 + 8727349 = 8728232
1021 + 8727211 = 8728232
1069 + 8727163 = 8728232
1123 + 8727109 = 8728232

Showing the first eight; more decompositions exist.
