Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505802, here are decompositions:

43 + 505759 = 505802
109 + 505693 = 505802
139 + 505663 = 505802
163 + 505639 = 505802
229 + 505573 = 505802
373 + 505429 = 505802
433 + 505369 = 505802
463 + 505339 = 505802

Showing the first eight; more decompositions exist.
