Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661916, here are decompositions:

17 + 8661899 = 8661916
149 + 8661767 = 8661916
173 + 8661743 = 8661916
227 + 8661689 = 8661916
233 + 8661683 = 8661916
293 + 8661623 = 8661916
359 + 8661557 = 8661916
479 + 8661437 = 8661916

Showing the first eight; more decompositions exist.
