Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165386, here are decompositions:

3 + 165383 = 165386
7 + 165379 = 165386
19 + 165367 = 165386
37 + 165349 = 165386
43 + 165343 = 165386
73 + 165313 = 165386
139 + 165247 = 165386
157 + 165229 = 165386

Showing the first eight; more decompositions exist.
