Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531472, here are decompositions:

89 + 531383 = 531472
113 + 531359 = 531472
173 + 531299 = 531472
191 + 531281 = 531472
233 + 531239 = 531472
269 + 531203 = 531472
401 + 531071 = 531472
449 + 531023 = 531472

Showing the first eight; more decompositions exist.
