Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8600872, here are decompositions:

53 + 8600819 = 8600872
83 + 8600789 = 8600872
89 + 8600783 = 8600872
131 + 8600741 = 8600872
233 + 8600639 = 8600872
239 + 8600633 = 8600872
251 + 8600621 = 8600872
281 + 8600591 = 8600872

Showing the first eight; more decompositions exist.
