Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554598, here are decompositions:

29 + 31554569 = 31554598
59 + 31554539 = 31554598
71 + 31554527 = 31554598
149 + 31554449 = 31554598
197 + 31554401 = 31554598
311 + 31554287 = 31554598
419 + 31554179 = 31554598
521 + 31554077 = 31554598

Showing the first eight; more decompositions exist.
