Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521954, here are decompositions:

31 + 521923 = 521954
67 + 521887 = 521954
73 + 521881 = 521954
163 + 521791 = 521954
211 + 521743 = 521954
283 + 521671 = 521954
313 + 521641 = 521954
373 + 521581 = 521954

Showing the first eight; more decompositions exist.
