Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732872, here are decompositions:

3 + 8732869 = 8732872
11 + 8732861 = 8732872
41 + 8732831 = 8732872
53 + 8732819 = 8732872
233 + 8732639 = 8732872
383 + 8732489 = 8732872
443 + 8732429 = 8732872
461 + 8732411 = 8732872

Showing the first eight; more decompositions exist.
