Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672198, here are decompositions:

37 + 8672161 = 8672198
97 + 8672101 = 8672198
151 + 8672047 = 8672198
211 + 8671987 = 8672198
487 + 8671711 = 8672198
727 + 8671471 = 8672198
751 + 8671447 = 8672198
757 + 8671441 = 8672198

Showing the first eight; more decompositions exist.
