Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732500, here are decompositions:

11 + 8732489 = 8732500
53 + 8732447 = 8732500
71 + 8732429 = 8732500
83 + 8732417 = 8732500
89 + 8732411 = 8732500
131 + 8732369 = 8732500
137 + 8732363 = 8732500
149 + 8732351 = 8732500

Showing the first eight; more decompositions exist.
