Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168488, here are decompositions:

7 + 168481 = 168488
31 + 168457 = 168488
37 + 168451 = 168488
79 + 168409 = 168488
97 + 168391 = 168488
157 + 168331 = 168488
211 + 168277 = 168488
241 + 168247 = 168488

Showing the first eight; more decompositions exist.
