Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162424, here are decompositions:

5 + 162419 = 162424
11 + 162413 = 162424
131 + 162293 = 162424
137 + 162287 = 162424
167 + 162257 = 162424
173 + 162251 = 162424
281 + 162143 = 162424
467 + 161957 = 162424

Showing the first eight; more decompositions exist.
