Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680420, here are decompositions:

3 + 8680417 = 8680420
11 + 8680409 = 8680420
29 + 8680391 = 8680420
41 + 8680379 = 8680420
83 + 8680337 = 8680420
107 + 8680313 = 8680420
113 + 8680307 = 8680420
191 + 8680229 = 8680420

Showing the first eight; more decompositions exist.
