Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554834, here are decompositions:

5 + 31554829 = 31554834
11 + 31554823 = 31554834
23 + 31554811 = 31554834
37 + 31554797 = 31554834
43 + 31554791 = 31554834
163 + 31554671 = 31554834
167 + 31554667 = 31554834
193 + 31554641 = 31554834

Showing the first eight; more decompositions exist.
