Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725884, here are decompositions:

7 + 8725877 = 8725884
43 + 8725841 = 8725884
53 + 8725831 = 8725884
61 + 8725823 = 8725884
67 + 8725817 = 8725884
71 + 8725813 = 8725884
127 + 8725757 = 8725884
151 + 8725733 = 8725884

Showing the first eight; more decompositions exist.
