Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531452, here are decompositions:

109 + 531343 = 531452
199 + 531253 = 531452
223 + 531229 = 531452
283 + 531169 = 531452
331 + 531121 = 531452
349 + 531103 = 531452
373 + 531079 = 531452
409 + 531043 = 531452

Showing the first eight; more decompositions exist.
