Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89740, here are decompositions:

59 + 89681 = 89740
71 + 89669 = 89740
83 + 89657 = 89740
107 + 89633 = 89740
113 + 89627 = 89740
137 + 89603 = 89740
149 + 89591 = 89740
173 + 89567 = 89740

Showing the first eight; more decompositions exist.
