Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162480, here are decompositions:

7 + 162473 = 162480
23 + 162457 = 162480
29 + 162451 = 162480
41 + 162439 = 162480
61 + 162419 = 162480
67 + 162413 = 162480
89 + 162391 = 162480
137 + 162343 = 162480

Showing the first eight; more decompositions exist.
