Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521672, here are decompositions:

3 + 521669 = 521672
13 + 521659 = 521672
31 + 521641 = 521672
139 + 521533 = 521672
181 + 521491 = 521672
271 + 521401 = 521672
313 + 521359 = 521672
373 + 521299 = 521672

Showing the first eight; more decompositions exist.
