Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162548, here are decompositions:

19 + 162529 = 162548
31 + 162517 = 162548
97 + 162451 = 162548
109 + 162439 = 162548
157 + 162391 = 162548
271 + 162277 = 162548
439 + 162109 = 162548
457 + 162091 = 162548

Showing the first eight; more decompositions exist.
