Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 183420, here are decompositions:

23 + 183397 = 183420
31 + 183389 = 183420
37 + 183383 = 183420
43 + 183377 = 183420
47 + 183373 = 183420
59 + 183361 = 183420
71 + 183349 = 183420
101 + 183319 = 183420

Showing the first eight; more decompositions exist.
