Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680442, here are decompositions:

3 + 8680439 = 8680442
73 + 8680369 = 8680442
139 + 8680303 = 8680442
193 + 8680249 = 8680442
223 + 8680219 = 8680442
229 + 8680213 = 8680442
241 + 8680201 = 8680442
271 + 8680171 = 8680442

Showing the first eight; more decompositions exist.
