Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 32890, here are decompositions:

3 + 32887 = 32890
47 + 32843 = 32890
59 + 32831 = 32890
89 + 32801 = 32890
101 + 32789 = 32890
107 + 32783 = 32890
173 + 32717 = 32890
197 + 32693 = 32890

Showing the first eight; more decompositions exist.
