Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732730, here are decompositions:

11 + 8732719 = 8732730
43 + 8732687 = 8732730
53 + 8732677 = 8732730
89 + 8732641 = 8732730
103 + 8732627 = 8732730
131 + 8732599 = 8732730
137 + 8732593 = 8732730
157 + 8732573 = 8732730

Showing the first eight; more decompositions exist.
