Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531402, here are decompositions:

19 + 531383 = 531402
43 + 531359 = 531402
59 + 531343 = 531402
71 + 531331 = 531402
103 + 531299 = 531402
139 + 531263 = 531402
149 + 531253 = 531402
163 + 531239 = 531402

Showing the first eight; more decompositions exist.
