Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520748, here are decompositions:

31 + 520717 = 520748
127 + 520621 = 520748
139 + 520609 = 520748
181 + 520567 = 520748
199 + 520549 = 520748
337 + 520411 = 520748
367 + 520381 = 520748
379 + 520369 = 520748

Showing the first eight; more decompositions exist.
