Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89984, here are decompositions:

7 + 89977 = 89984
61 + 89923 = 89984
67 + 89917 = 89984
151 + 89833 = 89984
163 + 89821 = 89984
313 + 89671 = 89984
331 + 89653 = 89984
373 + 89611 = 89984

Showing the first eight; more decompositions exist.
