Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551802, here are decompositions:

29 + 551773 = 551802
59 + 551743 = 551802
71 + 551731 = 551802
73 + 551729 = 551802
79 + 551723 = 551802
89 + 551713 = 551802
109 + 551693 = 551802
113 + 551689 = 551802

Showing the first eight; more decompositions exist.
