Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8601542, here are decompositions:

31 + 8601511 = 8601542
43 + 8601499 = 8601542
151 + 8601391 = 8601542
181 + 8601361 = 8601542
199 + 8601343 = 8601542
211 + 8601331 = 8601542
373 + 8601169 = 8601542
379 + 8601163 = 8601542

Showing the first eight; more decompositions exist.
