Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728892, here are decompositions:

43 + 8728849 = 8728892
181 + 8728711 = 8728892
229 + 8728663 = 8728892
283 + 8728609 = 8728892
313 + 8728579 = 8728892
379 + 8728513 = 8728892
409 + 8728483 = 8728892
421 + 8728471 = 8728892

Showing the first eight; more decompositions exist.
