Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531412, here are decompositions:

29 + 531383 = 531412
53 + 531359 = 531412
59 + 531353 = 531412
113 + 531299 = 531412
131 + 531281 = 531412
149 + 531263 = 531412
173 + 531239 = 531412
239 + 531173 = 531412

Showing the first eight; more decompositions exist.
