Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531434, here are decompositions:

97 + 531337 = 531434
103 + 531331 = 531434
181 + 531253 = 531434
271 + 531163 = 531434
313 + 531121 = 531434
331 + 531103 = 531434
457 + 530977 = 531434
487 + 530947 = 531434

Showing the first eight; more decompositions exist.
