Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521924, here are decompositions:

37 + 521887 = 521924
43 + 521881 = 521924
157 + 521767 = 521924
181 + 521743 = 521924
283 + 521641 = 521924
367 + 521557 = 521924
373 + 521551 = 521924
397 + 521527 = 521924

Showing the first eight; more decompositions exist.
