Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551844, here are decompositions:

31 + 551813 = 551844
43 + 551801 = 551844
71 + 551773 = 551844
101 + 551743 = 551844
113 + 551731 = 551844
127 + 551717 = 551844
131 + 551713 = 551844
151 + 551693 = 551844

Showing the first eight; more decompositions exist.
