Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661254, here are decompositions:

3 + 8661251 = 8661254
13 + 8661241 = 8661254
31 + 8661223 = 8661254
37 + 8661217 = 8661254
61 + 8661193 = 8661254
73 + 8661181 = 8661254
193 + 8661061 = 8661254
211 + 8661043 = 8661254

Showing the first eight; more decompositions exist.
