Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40210, here are decompositions:

17 + 40193 = 40210
41 + 40169 = 40210
47 + 40163 = 40210
59 + 40151 = 40210
83 + 40127 = 40210
173 + 40037 = 40210
179 + 40031 = 40210
197 + 40013 = 40210

Showing the first eight; more decompositions exist.
