Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89670, here are decompositions:

11 + 89659 = 89670
13 + 89657 = 89670
17 + 89653 = 89670
37 + 89633 = 89670
43 + 89627 = 89670
59 + 89611 = 89670
67 + 89603 = 89670
71 + 89599 = 89670

Showing the first eight; more decompositions exist.
