Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 56402, here are decompositions:

19 + 56383 = 56402
43 + 56359 = 56402
103 + 56299 = 56402
139 + 56263 = 56402
163 + 56239 = 56402
193 + 56209 = 56402
223 + 56179 = 56402
271 + 56131 = 56402

Showing the first eight; more decompositions exist.
