Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551742, here are decompositions:

11 + 551731 = 551742
13 + 551729 = 551742
19 + 551723 = 551742
29 + 551713 = 551742
53 + 551689 = 551742
71 + 551671 = 551742
83 + 551659 = 551742
89 + 551653 = 551742

Showing the first eight; more decompositions exist.
