Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501812, here are decompositions:

43 + 501769 = 501812
109 + 501703 = 501812
211 + 501601 = 501812
349 + 501463 = 501812
541 + 501271 = 501812
673 + 501139 = 501812
691 + 501121 = 501812
709 + 501103 = 501812

Showing the first eight; more decompositions exist.
