Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728078, here are decompositions:

5 + 8728073 = 8728078
41 + 8728037 = 8728078
89 + 8727989 = 8728078
179 + 8727899 = 8728078
269 + 8727809 = 8728078
311 + 8727767 = 8728078
347 + 8727731 = 8728078
389 + 8727689 = 8728078

Showing the first eight; more decompositions exist.
