Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501782, here are decompositions:

3 + 501779 = 501782
13 + 501769 = 501782
79 + 501703 = 501782
181 + 501601 = 501782
271 + 501511 = 501782
331 + 501451 = 501782
373 + 501409 = 501782
439 + 501343 = 501782

Showing the first eight; more decompositions exist.
