Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165584, here are decompositions:

31 + 165553 = 165584
43 + 165541 = 165584
61 + 165523 = 165584
73 + 165511 = 165584
127 + 165457 = 165584
193 + 165391 = 165584
241 + 165343 = 165584
271 + 165313 = 165584

Showing the first eight; more decompositions exist.
