Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681732, here are decompositions:

109 + 8681623 = 8681732
193 + 8681539 = 8681732
229 + 8681503 = 8681732
331 + 8681401 = 8681732
373 + 8681359 = 8681732
421 + 8681311 = 8681732
541 + 8681191 = 8681732
601 + 8681131 = 8681732

Showing the first eight; more decompositions exist.
