Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681432, here are decompositions:

3 + 8681429 = 8681432
31 + 8681401 = 8681432
73 + 8681359 = 8681432
181 + 8681251 = 8681432
211 + 8681221 = 8681432
241 + 8681191 = 8681432
373 + 8681059 = 8681432
439 + 8680993 = 8681432

Showing the first eight; more decompositions exist.
