Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552834, here are decompositions:

3 + 31552831 = 31552834
17 + 31552817 = 31552834
101 + 31552733 = 31552834
107 + 31552727 = 31552834
113 + 31552721 = 31552834
191 + 31552643 = 31552834
281 + 31552553 = 31552834
347 + 31552487 = 31552834

Showing the first eight; more decompositions exist.
