Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501802, here are decompositions:

23 + 501779 = 501802
71 + 501731 = 501802
83 + 501719 = 501802
101 + 501701 = 501802
179 + 501623 = 501802
239 + 501563 = 501802
383 + 501419 = 501802
401 + 501401 = 501802

Showing the first eight; more decompositions exist.
