Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531430, here are decompositions:

47 + 531383 = 531430
71 + 531359 = 531430
83 + 531347 = 531430
131 + 531299 = 531430
149 + 531281 = 531430
167 + 531263 = 531430
191 + 531239 = 531430
227 + 531203 = 531430

Showing the first eight; more decompositions exist.
