Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728066, here are decompositions:

29 + 8728037 = 8728066
167 + 8727899 = 8728066
257 + 8727809 = 8728066
293 + 8727773 = 8728066
443 + 8727623 = 8728066
467 + 8727599 = 8728066
569 + 8727497 = 8728066
653 + 8727413 = 8728066

Showing the first eight; more decompositions exist.
