Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552040, here are decompositions:

7 + 31552033 = 31552040
43 + 31551997 = 31552040
61 + 31551979 = 31552040
103 + 31551937 = 31552040
139 + 31551901 = 31552040
181 + 31551859 = 31552040
283 + 31551757 = 31552040
307 + 31551733 = 31552040

Showing the first eight; more decompositions exist.
