Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162488, here are decompositions:

31 + 162457 = 162488
37 + 162451 = 162488
97 + 162391 = 162488
199 + 162289 = 162488
211 + 162277 = 162488
379 + 162109 = 162488
397 + 162091 = 162488
409 + 162079 = 162488

Showing the first eight; more decompositions exist.
