Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732800, here are decompositions:

3 + 8732797 = 8732800
113 + 8732687 = 8732800
173 + 8732627 = 8732800
227 + 8732573 = 8732800
311 + 8732489 = 8732800
353 + 8732447 = 8732800
383 + 8732417 = 8732800
389 + 8732411 = 8732800

Showing the first eight; more decompositions exist.
