Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725124, here are decompositions:

13 + 8725111 = 8725124
73 + 8725051 = 8725124
103 + 8725021 = 8725124
157 + 8724967 = 8725124
181 + 8724943 = 8725124
241 + 8724883 = 8725124
277 + 8724847 = 8725124
337 + 8724787 = 8725124

Showing the first eight; more decompositions exist.
