Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 550890, here are decompositions:

29 + 550861 = 550890
31 + 550859 = 550890
47 + 550843 = 550890
59 + 550831 = 550890
79 + 550811 = 550890
89 + 550801 = 550890
101 + 550789 = 550890
127 + 550763 = 550890

Showing the first eight; more decompositions exist.
