Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551886, here are decompositions:

37 + 551849 = 551886
43 + 551843 = 551886
73 + 551813 = 551886
113 + 551773 = 551886
157 + 551729 = 551886
163 + 551723 = 551886
173 + 551713 = 551886
193 + 551693 = 551886

Showing the first eight; more decompositions exist.
