Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8750872, here are decompositions:

5 + 8750867 = 8750872
29 + 8750843 = 8750872
41 + 8750831 = 8750872
89 + 8750783 = 8750872
101 + 8750771 = 8750872
233 + 8750639 = 8750872
281 + 8750591 = 8750872
353 + 8750519 = 8750872

Showing the first eight; more decompositions exist.
