Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8733728, here are decompositions:

19 + 8733709 = 8733728
37 + 8733691 = 8733728
79 + 8733649 = 8733728
109 + 8733619 = 8733728
181 + 8733547 = 8733728
331 + 8733397 = 8733728
337 + 8733391 = 8733728
457 + 8733271 = 8733728

Showing the first eight; more decompositions exist.
