Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31551048, here are decompositions:

29 + 31551019 = 31551048
37 + 31551011 = 31551048
71 + 31550977 = 31551048
101 + 31550947 = 31551048
127 + 31550921 = 31551048
181 + 31550867 = 31551048
197 + 31550851 = 31551048
211 + 31550837 = 31551048

Showing the first eight; more decompositions exist.
