Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728592, here are decompositions:

13 + 8728579 = 8728592
43 + 8728549 = 8728592
79 + 8728513 = 8728592
109 + 8728483 = 8728592
211 + 8728381 = 8728592
283 + 8728309 = 8728592
331 + 8728261 = 8728592
463 + 8728129 = 8728592

Showing the first eight; more decompositions exist.
