Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 551132, here are decompositions:

3 + 551129 = 551132
19 + 551113 = 551132
73 + 551059 = 551132
139 + 550993 = 551132
163 + 550969 = 551132
181 + 550951 = 551132
193 + 550939 = 551132
223 + 550909 = 551132

Showing the first eight; more decompositions exist.
