Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531350, here are decompositions:

3 + 531347 = 531350
7 + 531343 = 531350
13 + 531337 = 531350
19 + 531331 = 531350
97 + 531253 = 531350
181 + 531169 = 531350
229 + 531121 = 531350
271 + 531079 = 531350

Showing the first eight; more decompositions exist.
