Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725028, here are decompositions:

7 + 8725021 = 8725028
61 + 8724967 = 8725028
79 + 8724949 = 8725028
157 + 8724871 = 8725028
181 + 8724847 = 8725028
229 + 8724799 = 8725028
241 + 8724787 = 8725028
307 + 8724721 = 8725028

Showing the first eight; more decompositions exist.
