Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554676, here are decompositions:

5 + 31554671 = 31554676
17 + 31554659 = 31554676
59 + 31554617 = 31554676
107 + 31554569 = 31554676
137 + 31554539 = 31554676
149 + 31554527 = 31554676
227 + 31554449 = 31554676
389 + 31554287 = 31554676

Showing the first eight; more decompositions exist.
