Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551842, here are decompositions:

29 + 551813 = 551842
41 + 551801 = 551842
89 + 551753 = 551842
113 + 551729 = 551842
149 + 551693 = 551842
191 + 551651 = 551842
293 + 551549 = 551842
353 + 551489 = 551842

Showing the first eight; more decompositions exist.
