Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728412, here are decompositions:

31 + 8728381 = 8728412
103 + 8728309 = 8728412
109 + 8728303 = 8728412
139 + 8728273 = 8728412
151 + 8728261 = 8728412
283 + 8728129 = 8728412
499 + 8727913 = 8728412
541 + 8727871 = 8728412

Showing the first eight; more decompositions exist.
