Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680072, here are decompositions:

29 + 8680043 = 8680072
101 + 8679971 = 8680072
173 + 8679899 = 8680072
281 + 8679791 = 8680072
431 + 8679641 = 8680072
491 + 8679581 = 8680072
521 + 8679551 = 8680072
719 + 8679353 = 8680072

Showing the first eight; more decompositions exist.
