Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657884, here are decompositions:

3 + 8657881 = 8657884
83 + 8657801 = 8657884
101 + 8657783 = 8657884
113 + 8657771 = 8657884
197 + 8657687 = 8657884
233 + 8657651 = 8657884
251 + 8657633 = 8657884
317 + 8657567 = 8657884

Showing the first eight; more decompositions exist.
