Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531370, here are decompositions:

11 + 531359 = 531370
17 + 531353 = 531370
23 + 531347 = 531370
71 + 531299 = 531370
83 + 531287 = 531370
89 + 531281 = 531370
107 + 531263 = 531370
131 + 531239 = 531370

Showing the first eight; more decompositions exist.
