Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86532, here are decompositions:

23 + 86509 = 86532
31 + 86501 = 86532
41 + 86491 = 86532
71 + 86461 = 86532
79 + 86453 = 86532
109 + 86423 = 86532
151 + 86381 = 86532
163 + 86369 = 86532

Showing the first eight; more decompositions exist.
