Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531926, here are decompositions:

7 + 531919 = 531926
79 + 531847 = 531926
103 + 531823 = 531926
127 + 531799 = 531926
313 + 531613 = 531926
337 + 531589 = 531926
379 + 531547 = 531926
673 + 531253 = 531926

Showing the first eight; more decompositions exist.
