Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89642, here are decompositions:

31 + 89611 = 89642
43 + 89599 = 89642
79 + 89563 = 89642
109 + 89533 = 89642
151 + 89491 = 89642
193 + 89449 = 89642
199 + 89443 = 89642
211 + 89431 = 89642

Showing the first eight; more decompositions exist.
