Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521912, here are decompositions:

31 + 521881 = 521912
43 + 521869 = 521912
103 + 521809 = 521912
163 + 521749 = 521912
241 + 521671 = 521912
271 + 521641 = 521912
331 + 521581 = 521912
373 + 521539 = 521912

Showing the first eight; more decompositions exist.
