Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531404, here are decompositions:

61 + 531343 = 531404
67 + 531337 = 531404
73 + 531331 = 531404
151 + 531253 = 531404
241 + 531163 = 531404
271 + 531133 = 531404
283 + 531121 = 531404
421 + 530983 = 531404

Showing the first eight; more decompositions exist.
