Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501842, here are decompositions:

13 + 501829 = 501842
73 + 501769 = 501842
139 + 501703 = 501842
151 + 501691 = 501842
241 + 501601 = 501842
331 + 501511 = 501842
349 + 501493 = 501842
379 + 501463 = 501842

Showing the first eight; more decompositions exist.
