Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554804, here are decompositions:

7 + 31554797 = 31554804
13 + 31554791 = 31554804
137 + 31554667 = 31554804
163 + 31554641 = 31554804
167 + 31554637 = 31554804
173 + 31554631 = 31554804
191 + 31554613 = 31554804
233 + 31554571 = 31554804

Showing the first eight; more decompositions exist.
