Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680090, here are decompositions:

17 + 8680073 = 8680090
47 + 8680043 = 8680090
53 + 8680037 = 8680090
137 + 8679953 = 8680090
191 + 8679899 = 8680090
347 + 8679743 = 8680090
449 + 8679641 = 8680090
509 + 8679581 = 8680090

Showing the first eight; more decompositions exist.
