Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728546, here are decompositions:

89 + 8728457 = 8728546
149 + 8728397 = 8728546
173 + 8728373 = 8728546
257 + 8728289 = 8728546
353 + 8728193 = 8728546
467 + 8728079 = 8728546
509 + 8728037 = 8728546
557 + 8727989 = 8728546

Showing the first eight; more decompositions exist.
