Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661798, here are decompositions:

29 + 8661769 = 8661798
31 + 8661767 = 8661798
71 + 8661727 = 8661798
109 + 8661689 = 8661798
157 + 8661641 = 8661798
227 + 8661571 = 8661798
241 + 8661557 = 8661798
269 + 8661529 = 8661798

Showing the first eight; more decompositions exist.
