Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672582, here are decompositions:

19 + 8672563 = 8672582
31 + 8672551 = 8672582
43 + 8672539 = 8672582
73 + 8672509 = 8672582
229 + 8672353 = 8672582
379 + 8672203 = 8672582
421 + 8672161 = 8672582
601 + 8671981 = 8672582

Showing the first eight; more decompositions exist.
