Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661404, here are decompositions:

151 + 8661253 = 8661404
163 + 8661241 = 8661404
181 + 8661223 = 8661404
211 + 8661193 = 8661404
223 + 8661181 = 8661404
421 + 8660983 = 8661404
457 + 8660947 = 8661404
541 + 8660863 = 8661404

Showing the first eight; more decompositions exist.
