Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680378, here are decompositions:

41 + 8680337 = 8680378
71 + 8680307 = 8680378
101 + 8680277 = 8680378
149 + 8680229 = 8680378
191 + 8680187 = 8680378
257 + 8680121 = 8680378
479 + 8679899 = 8680378
491 + 8679887 = 8680378

Showing the first eight; more decompositions exist.
