Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672186, here are decompositions:

139 + 8672047 = 8672186
199 + 8671987 = 8672186
349 + 8671837 = 8672186
547 + 8671639 = 8672186
613 + 8671573 = 8672186
739 + 8671447 = 8672186
823 + 8671363 = 8672186
937 + 8671249 = 8672186

Showing the first eight; more decompositions exist.
