Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162912, here are decompositions:

5 + 162907 = 162912
11 + 162901 = 162912
23 + 162889 = 162912
31 + 162881 = 162912
53 + 162859 = 162912
59 + 162853 = 162912
73 + 162839 = 162912
83 + 162829 = 162912

Showing the first eight; more decompositions exist.
