Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680144, here are decompositions:

23 + 8680121 = 8680144
41 + 8680103 = 8680144
71 + 8680073 = 8680144
101 + 8680043 = 8680144
107 + 8680037 = 8680144
173 + 8679971 = 8680144
191 + 8679953 = 8680144
257 + 8679887 = 8680144

Showing the first eight; more decompositions exist.
