Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552708, here are decompositions:

479 + 31552229 = 31552708
569 + 31552139 = 31552708
659 + 31552049 = 31552708
881 + 31551827 = 31552708
1109 + 31551599 = 31552708
1277 + 31551431 = 31552708
1301 + 31551407 = 31552708
1361 + 31551347 = 31552708

Showing the first eight; more decompositions exist.
