Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725118, here are decompositions:

7 + 8725111 = 8725118
19 + 8725099 = 8725118
67 + 8725051 = 8725118
79 + 8725039 = 8725118
97 + 8725021 = 8725118
151 + 8724967 = 8725118
271 + 8724847 = 8725118
331 + 8724787 = 8725118

Showing the first eight; more decompositions exist.
