Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 184420, here are decompositions:

3 + 184417 = 184420
11 + 184409 = 184420
83 + 184337 = 184420
149 + 184271 = 184420
179 + 184241 = 184420
233 + 184187 = 184420
239 + 184181 = 184420
263 + 184157 = 184420

Showing the first eight; more decompositions exist.
