Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8735872, here are decompositions:

11 + 8735861 = 8735872
23 + 8735849 = 8735872
59 + 8735813 = 8735872
83 + 8735789 = 8735872
191 + 8735681 = 8735872
239 + 8735633 = 8735872
251 + 8735621 = 8735872
263 + 8735609 = 8735872

Showing the first eight; more decompositions exist.
