Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89840, here are decompositions:

7 + 89833 = 89840
19 + 89821 = 89840
31 + 89809 = 89840
43 + 89797 = 89840
61 + 89779 = 89840
73 + 89767 = 89840
151 + 89689 = 89840
181 + 89659 = 89840

Showing the first eight; more decompositions exist.
