Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531368, here are decompositions:

31 + 531337 = 531368
37 + 531331 = 531368
139 + 531229 = 531368
199 + 531169 = 531368
379 + 530989 = 531368
421 + 530947 = 531368
457 + 530911 = 531368
499 + 530869 = 531368

Showing the first eight; more decompositions exist.
