Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728360, here are decompositions:

29 + 8728331 = 8728360
71 + 8728289 = 8728360
149 + 8728211 = 8728360
167 + 8728193 = 8728360
191 + 8728169 = 8728360
281 + 8728079 = 8728360
461 + 8727899 = 8728360
503 + 8727857 = 8728360

Showing the first eight; more decompositions exist.
