Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672066, here are decompositions:

3 + 8672063 = 8672066
19 + 8672047 = 8672066
79 + 8671987 = 8672066
229 + 8671837 = 8672066
397 + 8671669 = 8672066
433 + 8671633 = 8672066
547 + 8671519 = 8672066
619 + 8671447 = 8672066

Showing the first eight; more decompositions exist.
