Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162628, here are decompositions:

5 + 162623 = 162628
17 + 162611 = 162628
71 + 162557 = 162628
101 + 162527 = 162628
239 + 162389 = 162628
269 + 162359 = 162628
359 + 162269 = 162628
419 + 162209 = 162628

Showing the first eight; more decompositions exist.
