Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554766, here are decompositions:

17 + 31554749 = 31554766
107 + 31554659 = 31554766
149 + 31554617 = 31554766
197 + 31554569 = 31554766
227 + 31554539 = 31554766
239 + 31554527 = 31554766
293 + 31554473 = 31554766
317 + 31554449 = 31554766

Showing the first eight; more decompositions exist.
