Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162686, here are decompositions:

3 + 162683 = 162686
37 + 162649 = 162686
109 + 162577 = 162686
157 + 162529 = 162686
163 + 162523 = 162686
193 + 162493 = 162686
229 + 162457 = 162686
397 + 162289 = 162686

Showing the first eight; more decompositions exist.
