Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531068, here are decompositions:

79 + 530989 = 531068
157 + 530911 = 531068
199 + 530869 = 531068
211 + 530857 = 531068
271 + 530797 = 531068
337 + 530731 = 531068
367 + 530701 = 531068
409 + 530659 = 531068

Showing the first eight; more decompositions exist.
