Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725546, here are decompositions:

23 + 8725523 = 8725546
47 + 8725499 = 8725546
83 + 8725463 = 8725546
149 + 8725397 = 8725546
227 + 8725319 = 8725546
239 + 8725307 = 8725546
293 + 8725253 = 8725546
443 + 8725103 = 8725546

Showing the first eight; more decompositions exist.
