Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552208, here are decompositions:

139 + 31552069 = 31552208
151 + 31552057 = 31552208
211 + 31551997 = 31552208
229 + 31551979 = 31552208
271 + 31551937 = 31552208
307 + 31551901 = 31552208
349 + 31551859 = 31552208
487 + 31551721 = 31552208

Showing the first eight; more decompositions exist.
