Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661876, here are decompositions:

5 + 8661871 = 8661876
37 + 8661839 = 8661876
107 + 8661769 = 8661876
109 + 8661767 = 8661876
149 + 8661727 = 8661876
173 + 8661703 = 8661876
193 + 8661683 = 8661876
233 + 8661643 = 8661876

Showing the first eight; more decompositions exist.
