Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162420, here are decompositions:

7 + 162413 = 162420
29 + 162391 = 162420
31 + 162389 = 162420
61 + 162359 = 162420
127 + 162293 = 162420
131 + 162289 = 162420
151 + 162269 = 162420
157 + 162263 = 162420

Showing the first eight; more decompositions exist.
