Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8708872, here are decompositions:

23 + 8708849 = 8708872
41 + 8708831 = 8708872
131 + 8708741 = 8708872
233 + 8708639 = 8708872
251 + 8708621 = 8708872
281 + 8708591 = 8708872
353 + 8708519 = 8708872
443 + 8708429 = 8708872

Showing the first eight; more decompositions exist.
