Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 184090, here are decompositions:

3 + 184087 = 184090
17 + 184073 = 184090
47 + 184043 = 184090
59 + 184031 = 184090
83 + 184007 = 184090
131 + 183959 = 184090
173 + 183917 = 184090
281 + 183809 = 184090

Showing the first eight; more decompositions exist.
