Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501742, here are decompositions:

11 + 501731 = 501742
23 + 501719 = 501742
41 + 501701 = 501742
83 + 501659 = 501742
149 + 501593 = 501742
179 + 501563 = 501742
239 + 501503 = 501742
359 + 501383 = 501742

Showing the first eight; more decompositions exist.
