Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672144, here are decompositions:

43 + 8672101 = 8672144
97 + 8672047 = 8672144
157 + 8671987 = 8672144
163 + 8671981 = 8672144
307 + 8671837 = 8672144
433 + 8671711 = 8672144
571 + 8671573 = 8672144
643 + 8671501 = 8672144

Showing the first eight; more decompositions exist.
