Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165698, here are decompositions:

31 + 165667 = 165698
97 + 165601 = 165698
109 + 165589 = 165698
139 + 165559 = 165698
157 + 165541 = 165698
229 + 165469 = 165698
241 + 165457 = 165698
307 + 165391 = 165698

Showing the first eight; more decompositions exist.
