Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521434, here are decompositions:

5 + 521429 = 521434
41 + 521393 = 521434
71 + 521363 = 521434
167 + 521267 = 521434
191 + 521243 = 521434
233 + 521201 = 521434
257 + 521177 = 521434
281 + 521153 = 521434

Showing the first eight; more decompositions exist.
