Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672228, here are decompositions:

67 + 8672161 = 8672228
127 + 8672101 = 8672228
181 + 8672047 = 8672228
241 + 8671987 = 8672228
709 + 8671519 = 8672228
727 + 8671501 = 8672228
757 + 8671471 = 8672228
787 + 8671441 = 8672228

Showing the first eight; more decompositions exist.
