Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725618, here are decompositions:

47 + 8725571 = 8725618
71 + 8725547 = 8725618
107 + 8725511 = 8725618
137 + 8725481 = 8725618
197 + 8725421 = 8725618
227 + 8725391 = 8725618
257 + 8725361 = 8725618
311 + 8725307 = 8725618

Showing the first eight; more decompositions exist.
