Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162698, here are decompositions:

7 + 162691 = 162698
97 + 162601 = 162698
181 + 162517 = 162698
199 + 162499 = 162698
241 + 162457 = 162698
307 + 162391 = 162698
409 + 162289 = 162698
421 + 162277 = 162698

Showing the first eight; more decompositions exist.
