Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551850, here are decompositions:

7 + 551843 = 551850
37 + 551813 = 551850
41 + 551809 = 551850
83 + 551767 = 551850
97 + 551753 = 551850
107 + 551743 = 551850
127 + 551723 = 551850
137 + 551713 = 551850

Showing the first eight; more decompositions exist.
