Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551874, here are decompositions:

13 + 551861 = 551874
31 + 551843 = 551874
61 + 551813 = 551874
73 + 551801 = 551874
101 + 551773 = 551874
107 + 551767 = 551874
131 + 551743 = 551874
151 + 551723 = 551874

Showing the first eight; more decompositions exist.
