Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732784, here are decompositions:

41 + 8732743 = 8732784
97 + 8732687 = 8732784
107 + 8732677 = 8732784
131 + 8732653 = 8732784
157 + 8732627 = 8732784
191 + 8732593 = 8732784
211 + 8732573 = 8732784
233 + 8732551 = 8732784

Showing the first eight; more decompositions exist.
