Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551992, here are decompositions:

11 + 551981 = 551992
29 + 551963 = 551992
41 + 551951 = 551992
59 + 551933 = 551992
83 + 551909 = 551992
131 + 551861 = 551992
149 + 551843 = 551992
179 + 551813 = 551992

Showing the first eight; more decompositions exist.
