Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31555022, here are decompositions:

3 + 31555019 = 31555022
61 + 31554961 = 31555022
73 + 31554949 = 31555022
139 + 31554883 = 31555022
181 + 31554841 = 31555022
193 + 31554829 = 31555022
199 + 31554823 = 31555022
211 + 31554811 = 31555022

Showing the first eight; more decompositions exist.
