Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552002, here are decompositions:

5 + 31551997 = 31552002
23 + 31551979 = 31552002
43 + 31551959 = 31552002
61 + 31551941 = 31552002
101 + 31551901 = 31552002
149 + 31551853 = 31552002
199 + 31551803 = 31552002
269 + 31551733 = 31552002

Showing the first eight; more decompositions exist.
