Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501824, here are decompositions:

3 + 501821 = 501824
7 + 501817 = 501824
223 + 501601 = 501824
313 + 501511 = 501824
331 + 501493 = 501824
373 + 501451 = 501824
397 + 501427 = 501824
457 + 501367 = 501824

Showing the first eight; more decompositions exist.
