Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165470, here are decompositions:

7 + 165463 = 165470
13 + 165457 = 165470
73 + 165397 = 165470
79 + 165391 = 165470
103 + 165367 = 165470
127 + 165343 = 165470
139 + 165331 = 165470
157 + 165313 = 165470

Showing the first eight; more decompositions exist.
