Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661814, here are decompositions:

47 + 8661767 = 8661814
71 + 8661743 = 8661814
107 + 8661707 = 8661814
131 + 8661683 = 8661814
173 + 8661641 = 8661814
191 + 8661623 = 8661814
233 + 8661581 = 8661814
257 + 8661557 = 8661814

Showing the first eight; more decompositions exist.
