Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531374, here are decompositions:

31 + 531343 = 531374
37 + 531337 = 531374
43 + 531331 = 531374
211 + 531163 = 531374
241 + 531133 = 531374
271 + 531103 = 531374
331 + 531043 = 531374
397 + 530977 = 531374

Showing the first eight; more decompositions exist.
