Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725888, here are decompositions:

11 + 8725877 = 8725888
47 + 8725841 = 8725888
71 + 8725817 = 8725888
89 + 8725799 = 8725888
131 + 8725757 = 8725888
257 + 8725631 = 8725888
317 + 8725571 = 8725888
389 + 8725499 = 8725888

Showing the first eight; more decompositions exist.
