Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680400, here are decompositions:

31 + 8680369 = 8680400
73 + 8680327 = 8680400
97 + 8680303 = 8680400
103 + 8680297 = 8680400
151 + 8680249 = 8680400
181 + 8680219 = 8680400
199 + 8680201 = 8680400
229 + 8680171 = 8680400

Showing the first eight; more decompositions exist.
