Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672528, here are decompositions:

19 + 8672509 = 8672528
181 + 8672347 = 8672528
367 + 8672161 = 8672528
541 + 8671987 = 8672528
547 + 8671981 = 8672528
691 + 8671837 = 8672528
859 + 8671669 = 8672528
1009 + 8671519 = 8672528

Showing the first eight; more decompositions exist.
