Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554634, here are decompositions:

3 + 31554631 = 31554634
17 + 31554617 = 31554634
107 + 31554527 = 31554634
233 + 31554401 = 31554634
347 + 31554287 = 31554634
491 + 31554143 = 31554634
557 + 31554077 = 31554634
641 + 31553993 = 31554634

Showing the first eight; more decompositions exist.
