Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661274, here are decompositions:

23 + 8661251 = 8661274
71 + 8661203 = 8661274
101 + 8661173 = 8661274
113 + 8661161 = 8661274
137 + 8661137 = 8661274
227 + 8661047 = 8661274
353 + 8660921 = 8661274
383 + 8660891 = 8661274

Showing the first eight; more decompositions exist.
