Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165558, here are decompositions:

5 + 165553 = 165558
7 + 165551 = 165558
17 + 165541 = 165558
31 + 165527 = 165558
47 + 165511 = 165558
79 + 165479 = 165558
89 + 165469 = 165558
101 + 165457 = 165558

Showing the first eight; more decompositions exist.
