Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732736, here are decompositions:

17 + 8732719 = 8732736
59 + 8732677 = 8732736
83 + 8732653 = 8732736
97 + 8732639 = 8732736
109 + 8732627 = 8732736
137 + 8732599 = 8732736
163 + 8732573 = 8732736
263 + 8732473 = 8732736

Showing the first eight; more decompositions exist.
