Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550830, here are decompositions:

17 + 550813 = 550830
19 + 550811 = 550830
29 + 550801 = 550830
41 + 550789 = 550830
67 + 550763 = 550830
73 + 550757 = 550830
97 + 550733 = 550830
109 + 550721 = 550830

Showing the first eight; more decompositions exist.
