Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531362, here are decompositions:

3 + 531359 = 531362
19 + 531343 = 531362
31 + 531331 = 531362
109 + 531253 = 531362
193 + 531169 = 531362
199 + 531163 = 531362
229 + 531133 = 531362
241 + 531121 = 531362

Showing the first eight; more decompositions exist.
