Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732728, here are decompositions:

41 + 8732687 = 8732728
89 + 8732639 = 8732728
101 + 8732627 = 8732728
227 + 8732501 = 8732728
239 + 8732489 = 8732728
281 + 8732447 = 8732728
311 + 8732417 = 8732728
317 + 8732411 = 8732728

Showing the first eight; more decompositions exist.
