Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 159290, here are decompositions:

3 + 159287 = 159290
67 + 159223 = 159290
97 + 159193 = 159290
193 + 159097 = 159290
211 + 159079 = 159290
277 + 159013 = 159290
331 + 158959 = 159290
349 + 158941 = 159290

Showing the first eight; more decompositions exist.
