Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661374, here are decompositions:

151 + 8661223 = 8661374
157 + 8661217 = 8661374
181 + 8661193 = 8661374
193 + 8661181 = 8661374
313 + 8661061 = 8661374
331 + 8661043 = 8661374
373 + 8661001 = 8661374
487 + 8660887 = 8661374

Showing the first eight; more decompositions exist.
